The temperature at which a liquid boils is called this.
What is the boiling point?
300
He discovered that when the pressure of a gas constant temperature is increased, the volume of the gas decreases. When the pressure is decreased, the volume increases.
Who is Boyle?
300
Vaporization that takes place at the surface of a liquid.
What is evaporation?
300
This is the result of an inward pull among the molecules of a liquid that brings the molecules of the surface closer.
What is surface tension?
400
This has no definite shape but has a definite volume.
What is a liquid?

The change in state from a solid to a liquid is called this.
What is melting?
400
He found that when the temperature of a gas is increased at constant pressure its volume increases. When the temperature of a gas decreased at constant pressure, its volume decreases.

When the temperature of a gas decreases, the pressure of a gas does this.
What is decreases?
500
When the surface particles of a solid gain enough energy that they form a gas.
