Introduction to Unit 2: Thermal Energy, Temperature, and Heat

Today:

1) Homework due next class (write in homework notebook)

2) Review states of matter/Kinetic Particle Theory

3) Introduce Energy

Energy• is what moves matter.

• Remember: Matter is a solid, liquid, gas.

• Can you draw a diagram of the particles in 3 states of matter?

Solid Liquid Gas

All particles MOVE

• Solid, liquid, and gas particles are ALWAYS MOVING.

• They have KINETIC ENERGY.

• Kinetic Energy is energy of motion.

Energy allows particles to change state

Give an example of ENERGY:

• Kinetic• Thermal• Wind
