In this paper I will discuss how does the study of heat relate to the kinetic theory of matter, what heat is, what temperature is. I will also discover what the relationship between heat and temperature and how they are different. Lastly I will cover the various properties of a substance that determine its heat capacity and what various sources of heat there is.

Heat is a function of the velocity of all the molecules of a substance. Kinetic theory and heat transfer are both in motion, in Kinetic theory all states of matter are in vigorous motion and heat transfer is associated with the motion of atoms or molecules. The kinetic theory of matter says that all matter is made of particles that are in constant motion. Matter is made of constantly moving particles, which tells us how the matter in solids, liquids, and gases behaves. The reason heat relates to the kinetic theory is because, gases consist of great numbers of molecules moving in all directions, and that their impact on a surface causes the gas pressure to rise. According to http://www.qrg.northwestern.edu/projects/vss/docs/thermal/1-what-is-heat.html heat is energy. “Heat travels in waves like other forms of energy, and can change the matter it touches. It can heat it up-which starts molecules moving or it can cause chemical reactions like burning to occur. Heat can be released through a chemical reaction (such as the nuclear reactions that make the Sun "burn") or can be trapped for a limited time by insulators. It is often released along with other kinds of energy such as light, radio waves, or sound waves. A burning candle releases light and heat waves; an explosion releases light, heat, and sound waves. The Sun releases all kinds of energy waves. (1)” According to http://coolcosmos.ipac.caltech.edu “Temperature is a measure of the average heat or thermal energy of the particles in a substance. Since it is an average...
