Kinetic Theory and Thermal Energy

The 3 assumptionss of the kinetic theory are

• that all matter is composed of small particles

• the basic unit of matter is the cell

• the particles of matter are in constant random motion

• the particles are colliding with each other (and the walls of their container)
