boiling point

Boiling point is the temperature at which a liquid changes into a gas throughout the entire substance, not just at its surface. This occurs when the vapor pressure of the liquid equals the atmospheric pressure surrounding it. At this temperature, bubbles of vapor form within the liquid and rise to the surface, causing boiling. Each substance has its own boiling point, which can vary depending on pressure; for example, water boils at 100°C (212°F) at standard atmospheric pressure. The boiling point is an important property used in cooking, industrial processes, and scientific measurements.
