Why does water get cooled in evaporation?
It takes energy to boost a liquid or solid into a gaseous state, so an evaporating substance must aborsb thermal energy.
Does it mean that substance at a gaseous state does not have attraction forces?
NO it does not mean that substance at a gaseous state does not have attraction forces . It simply means that they have very very very weak forces of attraction . Therefore they have very high kinetic energy as compared to other physical states.
Which change in state requires that energy be added to the substance?
A phase change from solid to liquid requires energy .likewise a liquid will vaporise into the gaseous state after appropriate increase in energy.
