What is thermal expansion?

Back

The phenomenon where most substances expand when they are heated.

What is thermal equilibrium?

Back

When energy transfer between two objects stops because they are at the same temperature.

Front

What are insulators?

Back

Materials that do not allow heat to pass through easily, like rubber or plastic on electrical cords.

Front

What is potential energy?

Back

Stored energy that can be used later.
