Thermal Energy Review

​ Thermal & Kinetic Energy Quick Review

Multiple Choice

Energy comes in the form of...

• Heat, Light, and Sound

• Heat and Light

• Sound, Matter, and Heat

• Heat and Light

Remember...

​Energy is just that--it's energy. NOT MATTER!

Energy comes in many forms--for this unit, we have focused on Thermal Energy and Kinetic Energy the most.

Energy is NOT a phase or state of matter.

Multiple Choice

Kinetic Energy is the energy of...

• Motion

• Heat

• Sound

Multiple Choice

Thermal Energy is...

• The total amount of Kinetic Energy in an object/system

• The average amount of energy in an object system

• The energy of light

• Chemical energy

​Each state/phase of matter has a specific arrangement. Solids, liquids, and gasses all look differently at the molecular level. We can analyze these structures to see what state we are dealing with.

​States of Matter

Multiple Choice

What state is model B?

• Liquid

• Solid

• Gas

Thermal Energy and Matter

We can add Thermal Energy to something and things can change. When we add enough TE to a solid, for example, we can witness a phase change to a liquid. Add enough TE to a liquid? Gas.
