How does thermal energy play a role in particle motion and changes of state?
Thermal energy is a term that refers to temperature
Increasing an object's thermal energy increases particle motion and can cause a change of state.
Decreasing an object's thermal energy increases particle motion and can cause a change of state.
Thermal energy is the energy added from a heat source.
