Assignment #2: Paper Due Week Four:
In a documented essay of 900 - 1200 words please address the following issues, in your own words: * How does the study of heat relate to the kinetic theory of matter? * What is heat? * What is temperature? * What is the relationship between heat and temperature? * How are they different? * What are the various properties of a substance that determine its heat capacity? * What are the various sources of heat?

Conclusions about the structure of matter have been developed by physicists and chemists over the past 150 years. To understand it further let us look at the structure and the processes that occur to determine the state in which it exits.
Matter typically exists in 3 common states or phases: solids, liquids, and gases. It is made up of molecules. “A molecule is the smallest particle of a compound or a gaseous element that can exist and still retain the characteristic properties of that substance” (Tillery, B., Enger, E., Ross, F., Integrated Science 2009 Custom Edition, p.98). According to the Kinetic theory of matter, these molecules are in constant, random motion. Through the force of cohesion, molecules interact and attract each other. In the case of solids, which have a definite shape and volume, the molecules vibrate “in a fixed equilibrium position with strong cohesive forces” (Tillery, B., Enger, E., Ross, F., Integrated Science 2009 Custom Edition, p.98). The cohesive forces of liquids are strong enough to give it a specific volume, but not a definite shape. Gas molecules are far apart, move randomly and freely, and have weak cohesive forces.
This molecular motion is affected by temperature and determines the state, or phase, of matter as well as its kinetic energy. Molecular motion for…...

Nanotechnology Essay for Physical Science

...Nanotechnology Nanotechnology is defined as the understanding and control of matter at a very small scale which is called nanoscale. This type of science involves all different aspects like measuring, imaging, modeling and manipulation of matter at the nanoscale length. A Nano is so small that it is one billionth of a meter. In one inch there are 25,400,000 nanometers. The thickness of a sheet of paper is around 100,000 nanometers thick. As you can see, these are very tiny. This became popular in the 1980s by a man name K.Eric Drexler; that wanted to build machines from the nanometer. The Feynman theory was not to change the laws of physics but to enhance the possibility of maneuvering things atom by atom. Some new research in nanotechnology are developing nano-structures that will be able to tell the diseased cells from the healthy ones and then deliver the needed drugs directly to the cancerous tumors with no harm the healthy cells or to any other organs. Solar panels are another, because when using nanotechnology they are far more efficient than using standard designs that are now being use to convert sunlight to electricity. In return, solar power panels would be much more affordable. Researchers have also discovered that really small specks of rust can help remove arsenic from our drinking water. Imagine a fabric that is woven from tiny wires and that will absorb 20 times its weight in oil. A nano-fabric is being research and may be available for use in the near......

...Lab Research Report 1: Procedures in the Physical Sciences Robert Hugee Professor Brian McCann SCI110024VA016-1134-001: Introduction To Physical Science April 25, 2013 One of the underlying challenges in astronomy measurement is the determination of precise distances. Without a knowledge of its distance, the size of an observed object in space would remain nothing more than an angular diameter, and the brightness of a star could not be converted into its true radiated power, or luminosity .astronomy. (2013).  Direct measurement of the wavefunction had also long been deemed impossible because of the key tenet of the uncertainty principle. University of Rochester (2013, March 3). Getting around the uncertainty principle: Physicists make first direct measurements of polarization states of light. ScienceDaily. Large-scale surveying & mapping problems are also key challenges in making direct Measurements in astronomy. Pogge R.(2006) One of the indirect forms that the scientists have used is to resort to GEOMETRY to find the Distance. Parallax is one of the indirect methods where astronomers can measure the position of a nearby star very carefully with respect to more distant stars behind it, then measuring those distances again six months later when the Earth is on the opposite side of its orbit. Allen J.,Boyd P. (1997,April 15) The limitation of parallax is that it just gives distances to stars tp up to a few thousand light Years and beyond......

Procedures in the Physical Science

...Procedures in the Physical Science Erica Taylor Introduction to Physical Science April 25, 2013 Procedures in the Physical Science Science is defined as the systematic knowledge of the physical or material world gained through observation and experimentation (science, n.d.). Science is an ongoing quest for knowledge and understanding of not only the world itself, but the universe as well. In order to accomplish this quest, scientists use many tools to measure and analyze a variety of elements and phenomena in order to have a clear understanding of why things are the way they are. There are times however when direct measurement of something is not an option requiring scientists to find alternate solutions. Astronomy is the scientific study of the universe and what it is comprised of such as stars and planets. A scientist cannot simply use a ruler to measure how far away a star actually is and therefore indirect measurement techniques are needed. One such technique is the parallax method which involves triangulation. By looking at a star and record its location and then looking at it again six months later, astronomers can measure the distance of the angle of viewing. Combining this information with the orbital diameter of Earth to the sun and a little bit of geometry, astronomers can see that the different angles produce different distances (How are astronomers, 2000). Objects in space aren’t the only challenges scientists face when trying to obtain......

The female body has several organs that stand out and are different when it comes to the male body. The female body has several organs that actually make them capable of living in the different surroundings. The organs allows the female to produce and carry babies. When you look at the below diagram of the female human body you can see the organs and how they function all together. The human female body has several organs that stand out that are different from the male body especially when it comes to the reproduction organs of a female body. The reproduction of the female human body has learned how to evolve in order to reproduce. The reproduction organs are the vital organs of creating new offspring to the human world. The next diagram will show the image of the main reproduction organs in the human female body. It shows all the organs that allows females to have the capability of producing new life in the human organism world. The human organs have learn how to adapt to each other and reproduce new life. The reproduction organs in a female body are quite disquiet allows you to see how reproduction take place in the human female body. In the human body organism the reproduction cycle starts when a male and female......

Physical Science of Sky Diving

...The Physical Science of Skydiving Vanessa Laine Gabriel Dr. Burkeen Westwood College The Physical Science of Skydiving Introduction Skydiving which is also known as parachuting, is the action and adventurous sport in which a volunteer exit takes place from an aircraft for returning back to earth with gravity aid with the help of parachute for slowing down throughout the last of the safe descent of earth. This action may or may not comprise of a specific amount of free fall, but a moment in which the parachute has not been set out and the body accelerates gradually to terminal velocity. In this paper, a discussion will be conducted on the physical science of the skydiving. Skydiving is performed as a competitive sport and a recreational activity, as well as it fulfill the deployment of the Airborne forces’ military personnel and rarely forest firefighters. When a parachute opens as, that will be completely inflated by 2,600 feet or 800 meters, (BBC News, 2009) and then the skydiver can control the speed and direction with toggles on the steering lines’ ends that are linked to the parachute’s trailing edges, and can intend for a safe landing and eventually arrive to a moderately tender stop. All the contemporary sport parachutes have ‘ram-air’ wings that are self-inflating and assist in controlling the direction and speed as per the linked paragliders. Purists in every sport would signify that paragliders have highly superior range and lift, but that parachutes are......

...LRR#1 Bryan Smith Lab Research Report # 1 Strayer University SCI 110.109GA063-1142-001 Introduction to Physical Science Professor Larry Smith January 27, 2014 The world has always been amazed with astronomy which is the study of earth, planets, space, and the universe as a whole. This is one of the oldest practice since the beginning of time. Many civilizations have studied this for years. This was before anyone came up with the idea to build a ship to visit other planets. People have always been amazed by the unknown, and this is why we still have people going to outer space to discover new things. The use of the research for studying outer space is known as Astronomy. According to the web dictionary Astronomy is the scientific study of the matter in outer space, especially the positions, dimensions, distribution, energy, and evolution of celestial bodies and phenomena (http://www.thefreedictionary.com). Early scientist could not just look up in the sky to measure how far away a star actually is and to see what else is up in space. There is other techniques and equipment is needed. Early scientist use a technique called triangulation. This was done by looking at a star and record its location. Then six months later scientist would look at the star again and measure the distance and record any changes (How are astronomers, 2000). The strength of an earthquake by measure the level of shaking on......

Intro to Physical Science

...Daniel Calderon SCI 110 Intro to Physical Science Strayer University Dr. Jack Crawford 03/09/2015 Scientific Method The scientific method is a way to ask and answer scientific questions by making observations and doing experiments. The steps of the scientific method are to: 1. Ask a question 2. Do background research 3.Construct a hypothesis. 4.Test your hypothesis by doing an experiment 5. Analyze your data and draw a conclusion. It is important for your experiment to be a fair test. A "fair test" occurs when you change only one factor (variable) and keep all other conditions the same. While scientists study how nature works, engineers create new things, such as products, websites, environments, and experiences. Hypothesis For my job as a police officer we do follow a similar course of action with the scientific method. I will break it down following the similar steps we use. In my example I will process a simple shoplifting to make it easier to understand. The first step would be to ask the question did the suspect shoplift. The second step do background research would consist of reviewing the video of the crime and determine if the suspect meet the requirements for the shoplifting. Did the suspect take an item, conceal it and then not render payment for the item? If the suspect did all three on video then you can use that as evidence. You can get eyewitness testimony from the loss prevention personnel and or others that witnessed the suspect......

Introduction to the Sciences

...Maria D. Velazquez Introduction to the Sciences Prof. Talley My selected chemical is BPA. So, let’s start by talking what is BPA is a chemical that is added to plastic to harden them while keeping them light. BPA plays the role as an industrial chemical that has been used to make certain plastics and resins since the 1960s. BPA is found in polycarbonate plastics and epoxy resins. Polycarbonate plastics are used in the containers of what we eat and drink. Epoxy resins are used to coat the inside of metal products, such as food cans, bottle tops and water supply lines. Some dental sealants and composites also may contain BPA. Research shows that BPA can seep into food or beverages from containers that are made with BPA. Exposure to BPA is a concern because of possible health effects of BPA on the brain, behavior and prostate gland of fetuses, infants and children. BPA is part of our modern world because is everywhere, water bottles, veggies cans, milk gallons, baby bottles, even in medicine bottles. The funny part is that 90% of us has BPA in our bodies. However, the Food and Drug Administration (FDA) has said that BPA is safe at the very low levels that occur in some foods. This assessment is based on review of hundreds of studies. But in 2010 the FDA changed their position because with the standardize test they can’t find evident conclusion, then again the problem is that other independent studies show the harms of BPA, and this is how they raise “some concern”....
