Thermal energy is the total kinetic energy of the atoms and molecules in a substance.

Front

What happens to thermal energy when ice melts?

Back

Thermal energy is added to the ice, causing it to change from solid to liquid.

Front

What is the relationship between temperature and thermal energy?

Back

Higher temperature means higher thermal energy due to increased atomic motion.
