Heat and Temperature
Heat and Temperature
Heat is often described by the average individual as being the change in temperature from hot to cold. “Often the concepts of heat and temperature are thought to be the same, but they are not.” Heat and Temperature, para. 2) Perhaps the reasoning behind the incorrect reasoning is that humans associate the two together because when heat is applied to an object the temperature rises. The kinetic theory of matter better explains the underlying cause as to what takes place when heat is being examined. To examine the heat capacity of a substance various properties exist, along with different forms of heat. When thought about, everyone has been exposed to heat in some type of way but never even question what has to happen in order to encounter that sensation. The textbook states that “the term heat is used to describe the “something” that moves between objects when two objects of different temperatures are brought together.’ ( Tillery , Bill W., Enger, Eldon D., Ross, Fredrick C. p.82) Temperature on the other hand, can be defined as the degree of hotness or coldness of an object. The two are related due to the fact that heat is energy and temperature is basically a number used to determine the energy given by the molecules within a substance, which directly relates to the kinetic energy. The kinetic theory of matter and heat coincide with each other because the theory states that all materials are made up of either particles, molecules or atoms that are constantly moving. As to which when heat is displayed it is said that thermal energy is being transferred from a higher temperature to a lower one, meaning that particles have basically started to speed up. The idea of heat and temperature may seem very complex, but only because it happens so fast that most individuals do not even have a clue as to what is causing the reaction that they get when they raise the temperature in order to get heat. There are many differences between
