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.
What happens to particles during changes of state between solid and liquid.
Particles move so fast they break from their fixed position.
Particles melt and become a liquid.
Particles find a circular orbit around an atom's nucleus.
Particles stop vibrating and change into their liquid form.
The temperature at which a liquid turns to a gas is called the _____ point.
boiling
freezing
amorphous
crystalline
What happens to pressure as temperature increases?
pressure stays the same
pressure decreases
pressure increases
As the temperature of a gas goes up, the
volume of the gas will get larger

the atoms will slow down
the pressure of the gas will get lower
As the pressure of a gas goes up, the
volume of the gas will get larger
volume of the gas will get smaller
the atoms will slow down
the pressure of the gas will get lower
