Evaporation is a physical change it is not a chemical change. There are three commonly known types of vaporization and they are boiling evaporation and sublimation. When water evaporates it changes from the liquid state to the gas state but it is still water.

Evaporation is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature andor pressure. It wouldnt be a chemical because in chemical changes substances can be made and destoyed like elements some are made in labs and some were discovered so substances and gases. Vaporization is the physical change that turns liquids or solids into vapor or gas.
