Temperature and Heat

Paper Summary:

This paper discusses the relationship between temperature and heat. It defines heat and temperature and discusses three core heat-related subjects that play important roles to better understand the study of thermal physics - thermodynamics, statistical mechanics, and kinetic theory. The paper examines the similarities and differences between heat and temperature.

From the Paper:

"Aside from the discussions we have made above, there are also other heat transfer mechanisms that we should know. These are latent heat and heat pipe. In latent heat, the transfer of heat results to a change in physical form such as water-to-ice or water-to-steam. When heat is transferred, the substance ice can be melted into water. If you will notice, this change does not cause a raise in temperature. Although heat is absorbed by this change of state, the absorbed energy is not used to speed up the molecules, but the energy was used to change the bonding between the molecules. These processes were utilized through the use of refrigerator, steam engine, and other mechanical and electrical devices. A refrigerator uses heat exchanger that is built for efficient heat transfer from one liquid to another. The fluids may be separated by a solid wall so that they never mix, or the fluids are directly contacted. Heat exchangers are also used in air conditioning, space heating, power production, and chemical processing. On the contrary, if a solid is heated through its melting point, it will melt and turn to liquid. Heat pipes, on the other side, can also carry many times as much heat as a similar-sized copper rod using latent heat and capillary action. Although the heat transfer in boiling fluid is complex, it is of considerable technical importance in the industry. Truly, temperature and heat are vital life."
