WitrynaCheeky. When water is heated up, it changes state from a liquid to a gas, called steam. And this process is called evaporation. When a gas cools down, it can change state back into a liquid. So ... Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. High concentration of the evaporating substance in the surrounding gas significantly slows down evaporation, such as when humidity affects rate of evaporation of water. When the molecules of the liquid collide, they transfer energy to each other based on how they collide. When a …

Witryna16 lut 2024 · In general, a vapour refers to the gas phase of a substance below critical temperature. This means that if pressure changes, the gas can become a liquid without a required temperature change. This can apply to any substance. Steam in general refers to the gas phase of water. Steam can be the same as water vapour in some contexts.
