A liquid can be changed into gas by hating.When liquids are heated they boil and change into their gaseous states.
When any liquid receives enough energy, it starts to change its kinetic energy level and go from just a liquid to a liquid and some gas. It can either change into a gas when it has reached its boiling point or it evaporates, which is just when surface molecules of a liquid get just enough energy to change states by themselves. Since you asked for examples, I’ll give you ten:
1.) Water boiling into steam.
2.) Liquid nitrogen boiling into gaseous nitrogen.
3.) Liquid helium boiling into gaseous helium.
4.) Mercury evaporating into… well, mercury fumes.
5.) Gasoline evaporating into gasoline fumes.
6.) Alcohols evaporating into alcohol fumes.
7.) Water leaving a hydrate and becoming water vapor.
8.) Decompressed refrigerants
9.) Liquid oxygen boiling into gaseous oxygen
10.) Basically any liquid passing through an orifice at enough pressure. (If you don’t know what an orifice is, think about an adapter for PVC, but instead of changing the pipe size, imagine it just forcing the liquid through a very small hole in the middle where the opening should be.)
