Thermal Energy

Matter and Thermal Energy

1. Energy Transfer and Temperature

• Engineering Challenge

2. Changes in Energy at the Molecular Level

3. Phase Changes and Energy Transfer

Guiding Questions:

How can we represent matter at the microscopic level?

When an object is hot, how is it different from when it is cold?

What happens when hot objects and cold objects interact?

What happens to the kinetic energy of an object when it crashes or collides with the ground and stops?
