The vapor pressure of water increases as the temperature is raised.

温度升高，水蒸汽气压增加。

So when I have a pure water solution, the total pressure is going to be the same as the vapor pressure of water at a particular temperature Let's take temperature fixed at some value.

当溶液是纯水时，总压强应该等于纯水，在特定温度下的蒸汽压，我们让温度固定。

Then I want to ask the question, what is the vapor pressure of the water?

现在我想问的是，水的蒸汽压是多少？

youdao

For example, when you heat a pan of water the vapor pressure increases until it reaches atmospheric pressure.
