The kinetic molecular theory explains how particles move and has three major points. What are they?
•All matter is made of particles. •Particles are in constant, random motion. •Particles constantly collide with each other and with the walls of their container.
The measure of the average kinetic energy of the particles in a material.
Temperature
The transfer of thermal energy by collisions between particles in matter.
Conduction
The transfer of thermal energy by electromagnetic
Radiation
The transfer of thermal energy by the movement of the particles from one part of a material to another.
Convection
The change of state from a liquid to a gas.
Vaporization
A material in which thermal energy moves quickly.
Thermal Conductor
A material in which thermal energy moves slowly.
Thermal Insulator
