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

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

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.
