Front

What is thermal energy?

Back

The energy that comes from the temperature of matter; it is the total kinetic energy of 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 an example of energy transformation in a wind turbine?
