This lesson

• Kinetic energy
• Exersises
• Discussing exersise 4 and 5
• New material

Goals – to answer these question

• What does it mean for a substnace to gain kinetic energy?
  
• What do you need to cause a phase change?
• What happens during a phase change?

To start

What happens to the particles in a substance when it gains heat (kinetic energy)?

What two things happen during a phase change?

Why does a phase change cost extra energy?

Discussing exersise 4 and 5

The new material

Goals – to answer these question
