What is the temperature at which water boils at sea level?

Water boils at 100 °C at sea level under standard atmospheric pressure. This boiling point is a fundamental property of water and is commonly used as a reference point in various scientific and practical applications. At this temperature, the vapor pressure of the water equals the atmospheric pressure surrounding it, allowing bubbles of vapor to form within the liquid.

Understanding the boiling point is crucial in fields such as cooking, chemistry, and various scientific disciplines, as it influences how water behaves under heat. While the other temperature options presented are below or above the actual boiling point, they do not reflect the standard physical property of water at sea level.
