"Boiling point" 是指物质在一定压力下的沸点，即物质从液态变为气态的温度。
以下是一篇关于 boiling point 的英文范文：
Boiling Point
In science, the boiling point of a substance is the temperature at which the substance changes from a liquid to a gas. This process occurs when the vapor pressure of the liquid exceeds the atmospheric pressure around it. For example, water has a boiling point of 100 degrees Celsius because at this temperature, the vapor pressure of water is equal to the atmospheric pressure, causing it to boil.
In our daily lives, we often use boiling points in cooking and other activities. When we cook food, we often use high temperatures to break down the food's molecules and release their flavors. This process occurs at the boiling point of water, which is why we use water to cook most foods.
Another example is in the chemical industry, where boiling points are used to separate substances based on their different vapor pressures. For instance, distillation is a process that uses boiling points to separate a mixture of substances into their pure forms.
Overall, the boiling point of a substance is an important property that determines how it behaves under certain conditions. Understanding this concept is crucial for understanding how substances interact with each other and how we can use them in our daily lives.
