The change of state from liquid to gas is called vaporization. This process occurs when a liquid gains enough energy, often through heat, causing its molecules to move apart and enter the gaseous state. Vaporization can happen via two methods: evaporation, which occurs at any temperature below the boiling point, and boiling, which occurs at the liquid's boiling point. Understanding vaporization is crucial in various scientific fields, including meteorology, cooking, and industrial applications.
