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.

Pressure effects changes of states because...
Particles confined to a smaller space can move less freely.
Particles are unable to change states under immense pressure.
Particles confined to a smaller space are able to change state with less thermal energy.
Pressure increases the thermal energy of particles.
An increase in the motion of molecules occurs when
heat energy changes randomly.
