• shape and position

• flow and radius

The temperature at which a solid begins to liquefy is its ______ point.

• freezing

• boiling

• melting

• mass

The amount of energy required for a liquid at its boiling point to become a gas is _____________.

• heat of fusion

• heat of vaporization

• transpiration

• freezing point

_______________ is an increase in the size of a substance when the temperature is increased.

• kinetic energy

• potential energy

• thermal point

• heat of vaporization

• heat of transformation

• melting point

• heat of fusion

When a gas becomes a liquid it is called

• condensation

• evaporation

• sublimation

• freezing

What is vaporization?

• The process of turning from solid to liquid

• The process of turning from gas to liquid

• The process of turning from liquid to solid
