What happens to the temperature of a sample of matter as it changes from a liquid to a gas?

When it changes from a liquid to a gas, the temperature increase because the process requires energy. A good example is boiling water, just think about how the liquid boils and water vapor came out.

All matter can move from one state to another. It may require extreme temperatures or extreme pressures, but it can be done. Sometimes a substance doesn't want to change states. You have to use all of your tricks when that happens. To create a solid, you might have to decrease the temperature by a huge amount and then add pressure. For example, oxygen (O2) will solidify at - 361.8 degrees Fahrenheit (-218.8 degrees Celsius) at standard pressure. However, it will freeze at warmer temperatures when the pressure is increased. i think
