The temperature at which a liquid evaporates is known as its boiling point. The boiling point varies depending on the specific liquid and the surrounding pressure. At the boiling point, the liquid changes into its gaseous state throughout the bulk of the liquid, resulting in the formation of vapor bubbles.
It's important to note that the boiling point is a characteristic property of a substance and remains constant at a given pressure. For example, the boiling point of water at standard atmospheric pressure (1 atmosphere) is 100 degrees Celsius (212 degrees Fahrenheit). However, the boiling point can be altered by changing the pressure. If the pressure is decreased, as in the case of high-altitude areas, the boiling point of a liquid will be lower. Conversely, if the pressure is increased, such as in a pressure cooker, the boiling point will be higher.
