What is the boiling point of water at sea level in Celsius?

The boiling point of water at sea level is 100 degrees Celsius. This temperature is defined as the point at which water transitions from a liquid to a gas, or vapor, as it absorbs heat energy. At sea level, the atmospheric pressure is approximately 101.3 kilopascals (kPa), which allows water to boil at this temperature.

In locations at higher altitudes, where the air pressure is lower, the boiling point of water decreases, causing it to boil at temperatures below 100 degrees Celsius. This property of water is critical in various scientific and culinary applications, where precise temperatures are essential for processes like cooking and chemical reactions. Understanding this concept is fundamental in both practical life and academic studies related to chemistry and physics.
