3. EQ How are kinetic energy and thermal energy in a substance related?

4. Kinetic molecular theory The kinetic molecular theory explains how particles move: 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.

5. Kinetic molecular theory SOLID: Particles close together, in a set position, slow vibration. LIQUID: Can change position, Further apart, Move faster. GAS: Even further apart and faster.

6. Kinetic molecular theory Temperature: The measure of the average kinetic energy of the particles in a material Temperature Thermal expansion volume increases as the temperature of the material increases. Kinetic Energy and thermal energy are directly proportional.

7. Kinetic molecular theory Heat: energy from High to low Heat When the temperatures are the same, the materials are in thermal equilibrium.
