What Is KMT?
The Kinetic Molecular Theory (KMT) theorizes that molecules move rapidly and randomly. Because of this many things change about the structure and nature of the molecules. A good example of KMT is when exercising. Your body temperature rises because of the kinetic energy building up because of friction and the stimulation of your heart. this causes sweat. Another example of KMT lies in weather and more specifically rainy weather. When water gains heat it evaporates, it then turns into gas that rises into the clouds. In the clouds, the water vapor rises gathers, grouping together, causing the water molecules to move slower and become heavier. Then, eventually they become to heavy to stay suspended in the sky and fall back to earth as rain which lands into water and begins the cycle again.
The basic underlying concepts of KMT are the following:
-All matter is made of moving particles
-These particles move all the time (except at 0 k)
-There are spaces between particles
-All particles have energy (amount of energy depends on phase)
-The temperature of a substance is the average kinetic energy of the particles that make up that substance
-Changes in phase happen with changes in energy

What is Kinetic energy? What is potential energy?
Kinetic Energy:
Energy is the ability to do work. Kinetic energy is the energy of a system in the process of working.
Potential Energy:
Potential energy is energy that is stored in a system, ready to do work but not working yet.
