Relation of Heat and Kinetic Theory of Matter 1 The Kinetic Theory of Matter declares that particles of matter in all states are in vigorous motion. And this theory can help us predict heat transfer. Unmistakably the transfer of heat is the kinetic energy caused by the jittering of atoms or molecules in a substance. The faster the particles move, more heat is produced and the farther apart the molecules can spread. This theory explains heat transfer by conduction. Thermal energy flows from the warmer object and through the cooler one warming it up. Heat 2 Heat is the transfer of one body or object to another through thermal contact. It is a form of energy all by itself. The transfer of heat is spontaneous and only flows towards the colder entity. And the energy transfer of heat can only be done as a result of conduction, convention, or radiation. Heat is based on the total internal energy of the molecules a body has. So what’s thought of as “cold” is truly just the absence of heat. Since heat is a way to transfer energy that means it can be measured. The metric unit of heat is a calorie or joule, and in Britain it’s a British thermal unit (Btu). Temperature 3 Temperature is defined as the measure of the average kinetic energy of the particles of a substance. It is not a form of energy but a means of energy transfer. And since it is an average of the heat or energy therefore the number of particles inside and size of the item don’t matter. It is the physical property emphasizing hot and cold. Generally an object that feels hot will have a high temperature. Or if an object feels warmer to the touch then it’s known that it has to be warmer than body temperature. But other than touch, thermometers are com... ... middle of paper ... ...natural gas too can all be utilized. Food is even considered a source of heat for bodies when eaten. Friction can also be a source of heat, when two items are rubber together they get warmer. Mechanical actions all create heat too, like factories or car brakes. Electrical energy can produce heat to defying elements. Also nuclear reactions cause leaps in the energy of molecules and this creates heat. When it comes down to it the list of everything that releases or produces heat is truly never ending. References Tillery, B. W., Enger, E. D., & Ross, F. C. (2008).
