What temperature does water boil at under standard atmospheric conditions?

Water boils at 100°C under standard atmospheric conditions, which is defined as one atmosphere of pressure (101.3 kPa or 760 mm Hg). At this temperature, the vapor pressure of water equals atmospheric pressure, allowing bubbles to form and the liquid to transition into vapor. This physical change is crucial in many scientific and practical applications, such as cooking and industrial processes.

The boiling point can vary with changes in atmospheric pressure; for example, at higher altitudes where pressure is lower, water will boil at a temperature lower than 100°C. Understanding the boiling point of water is fundamental in many scientific disciplines, such as chemistry and physics, as it relates to the properties of liquids and the behavior of molecules.
