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 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
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.
Melting point is a way to identify an unknown material.
Water temperature will stop increasing as ice is melting.
