Front

What is thermal energy?

Back

The total kinetic energy of all the particles in an object.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids and gases).

Front

What is radiation?

Back

The transfer of heat through electromagnetic waves.

Front

How does heat transfer in a vacuum?

Back

Through radiation only, as there are no particles to conduct or convect heat.
