1 Some Help With Tough Moisture Questions 1) Why does the saturation vapor pressure go up when the temperature goes up? The solid blue curve below describes how saturation vapor pressure of water changes with temperature. Notice that it goes up, rapidly, with temperature. Why? This goes back to the idea of “equilibrium.” Remember that saturation is really just an equilibrium between evaporation

2 and condensation over a water surface. The evolution to this equilibrium for 20°C is shown below: The number of molecules in the air at equilibrium determines the “saturation vapor pressure.” Even though the temperature of the water isn’t boiling, some of the water molecules do have enough energy to evaporate. Remember that temperature is the average kinetic energy of molecules.

3 Now, what if we turned up the temperature to 40°C in the figure above? Then the water molecules would have more average kinetic energy, and even more of them would have enough energy to be able to make the
