The boiling point of water at sea level is 100 degrees Celsius (212 degrees Fahrenheit). This temperature is a key physical property of water and signifies the point at which water transitions from a liquid to a gas, forming steam. The boiling point can vary depending on atmospheric pressure; for example, at higher altitudes, the boiling point of water decreases due to lower air pressure. This phenomenon is particularly important in cooking or scientific applications, where precise temperature control is necessary. Understanding the boiling point assists in various fields, including culinary arts, meteorology, and chemistry.
