# What is the temperature of evaporating water (not boiling)?

The vapor pressure of water at $\pu{70 ^\circ C}$ is $\pu{233.7torr}$.
If I were to put a temperature probe directly above the liquid water, what would it read?

In other words, does a water molecule need to have $\frac32kT$ (where $T=\pu{373 K}=\pu{100 ^\circ C}$) to escape the liquid?

• While it's a liquid water can escape what contains it due to the difference of chemical potential and it will escape until the thermodynamic equilibrum has not been reached. This is due to phenomenas of diffusion. You'll find some explaination there Apr 3 '17 at 23:01
