👉 In physics and chemistry, an "evaporative" process refers to a process that occurs when a substance is exposed to a gas. This gas can be air or other gases like nitrogen, oxygen, or carbon dioxide. For example, in the process of evaporation, water (or any liquid) is heated until it becomes vaporized into its liquid form. The heat from the stove causes the water molecules to gain energy and move up through the liquid state, eventually reaching a temperature where they can
