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.
What is a main difference between boiling and evaporation?
Boiling requires an outside power source and the evaporation process is internal.
Evaporation takes place at one temperature, boiling takes place at all temperatures.
Boiling takes place at one temperature, evaporation takes place at all temperatures.
Boiling takes can only occur through mechanical methods.
Boiling a liquid...
Has the opposite effect of evaporating a liquid.
Happens at a lower temperature at a lower altitude.
Decreases pressure inside of the liquid.
Increases pressure inside of the liquid.
The reverse of vaporization is...
Condensation
Sublimation
Deposition
Alienation
Condensation occurs when...
Liquid is condensed into a solid.
Water vapor becomes snow at high altitudes.
As a liquid is heated to boiling.
Vapor is cooled on a surface.
An example of sublimation is..
Dry ice turning into CO2
Water Freezing
Dry ice turning into H2O
Lava erupting from a volcano
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.
Water temperature will stop increasing as ice is melting.

Herbie makes a graph of the temperature of a solid as he heats it. What shape will the graph have?
A diagonal line that starts low and keeps going up the whole way.
A diagonal line that starts low, has a flat portion, then goes up again.
Gertrude is observing liquids at a birthday party. Some are sweet, some are hot, and some are sticky. If she could look at the particles of the liquids, which statement would be true?
The particles are far apart and moving fast, with no shape.
The particles may touch but they can flow past each other.
The particles are in close contact and cannot move from their places.
The particles have no arrangement.
