Heat and Kinetic Theory of Matter

Kinetic theory of matter is defined as a theory that matter is composed of small particles, all in random motion. Heat is defined as the motion of atoms and molecules that create a form of energy or thermal energy, which is present in all matter. Simply stated, heat is energy.

Heat relates to the theory of kinetic matter because gases consist of great numbers of molecules moving in all directions. Their impact on a surface causes the gas pressure that we feel, and that what we experience as heat is simply the kinetic energy of their motion.

The study of heat is explained through science. It is not a theory of sorts like kinetic theory of matter is. Heat is what makes kinetic energy. The more heat that is produced the higher the kinetic energy level of an object or substance is or has. The kinetic energy theory gives the differences of three states of matter; solids, liquids, and gases.

The result of heat in these three states of matter has different effects on each. For instance, if you gave the same amount of heat off for all three substances, gas would be the first to break apart because its particles are not tightly bound. A liquid substance would be the second to disperse because it has the ability to stretch against the forces of attraction. Solids, however, when induced by heat, will break apart the slowest of the three substances. The reaction of particles that are held so tightly together is not capable to travel like the particles in the other substances.

Heat travels in waves like other forms of energy, and can change the matter it touches. It can heat up what starts molecules moving or it can cause chemical reactions like burning to occur. Heat can be released through a chemical reaction, such as nuclear reactions. When heat is created, kinetic energy is created as well....
