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
