Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in an object, related to its temperature.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves, such as sunlight.

Front

What happens to the thermal energy of an object when it is heated?

Back

The thermal energy increases as the particles move faster.
