What occurs when a liquid becomes a gas?

When a liquid becomes a gas, the molecules move farther apart from each other. This process is known as vaporization or evaporation. As the temperature of the liquid increases, the energy of the molecules increases, allowing them to overcome the intermolecular forces that keep them close together in the liquid state. As the molecules gain enough energy, they can escape the liquid's surface and enter the gas phase, resulting in a greater distance between them compared to their arrangement in the liquid state. This transition is essential in various natural processes and everyday occurrences, such as boiling water or when sweat evaporates from the skin.
