Why does water evaporate spontaneously at room temperature despite ΔG > 0?

Put nothing but water in it, set the heat bath to 25 C, and adjust the volume so the pressure is 1 atmosphere. Since the vapor pressure of water at 25 C is 0.0313 atmospheres, there will be no vapor, the piston will be in contact with the liquid water, pressing down with one atmosphere pressure. Your equation and conclusions are correct.

Q & A: water temperatures | Department of Physics | University of …

A: It is not true that water can only get up to 212 degrees and as cold as 32 degrees. After water changes from a liquid to a gas (at 212 degrees Fahrenheit) it can actually heat up much hotter than that. In the gas form, water molecules are spread out and have a lot of room to move and get much hotter than the other two phases (liquid and ice).

At what temperature will water evaporate? – AskingLot.com

This means that at 100°C, you can have pure water vapor at atmospheric pressure. This is why water boils at 100°C at sea level—a bubble of steam can form below the surface of the water. Does water evaporate at 0 degrees? Water less than 0 can evaporate or sublimate. It depends on what is dissolved in it, or how pure it is.

It’s Water Vapor, Not the CO2 – American Chemical Society

The warming due to increasing non-condensable gases causes more water vapor to enter the atmosphere, which adds to the effect of the non-condensables. There is also a possibility that adding more water vapor to the atmosphere could produce a negative feedback effect. This could happen if more water vapor leads to more cloud formation.
