The term for the temperature at which a liquid turns into a gas is called its boiling point. This temperature varies among liquids and is influenced by atmospheric pressure. At the boiling point, the vapor pressure of the liquid equals the external pressure surrounding it, allowing molecules to escape into the gas phase. Understanding boiling points is crucial in various scientific fields, such as chemistry and cooking, as it influences phase transitions and energy transfer. It also plays a significant role in applications like distillation and food preparation.
