The term "matter" refers to any substance that occupies space and has weight. It comprises of atoms and molecules that are constantly in motion due to energy that they possess. Energy is present in all matter mostly in form of heat energy. Energy takes various forms and can change from one form to another form (Alefeld & Radermacher, 1993, p. 9). Other than heat energy, various forms of energy include electrical, light, mechanical, chemical, sound and nuclear energy. These different forms of energy can cause a substance to heat up by simply increasing the speed of the molecules in the matter. Molecules therefore, have characteristics of warmth and coldness depending on the form of energy they possess. Since the particles are constantly moving, they possess kinetic energy, which is also one of the various forms of energy. .
Relationship Between Heat and Kinetic Theory of Matter.
Kinetic theory of matter explains that, matter is in a constant random movement. Applying heat on molecules cause the particulars to move in a random motion. Heating transfers heat to nearby molecules in a substance, which becomes excited and then stimulates the surrounding molecules into motion. The process of molecules excitation continues until all molecules move in a vigorous random motion. In this process of molecules excitation, the kinetic theory of matter links together with heat.
Heat.
Heat is the transfer of energy that results from temperature difference between two objects or systems. At molecular level, heat refers to the transfer of energy that stimulates disordered molecules. For example, the burning of a hydrocarbon fuel releases energy that stimulates the surrounding atoms and molecules into a random motion. Transfer of heat energy is measured in calorimetric units. The process of taking this measurement is by observing the rise in temperature. Calorimetric units measures internal energy changes and enthalpy that accompany a chemical reaction.
