Question

A propane tank sits outside with its valve closed. In other words, no molecules can get into or out of the tank. On a cold night, almost all of the propane in the tank condenses into a liquid inside the tank. Its mass on a cold night is exactly 10.0 kg. The next day is warmer, so some of the propane inside the tank evaporates into a gas inside the tank. Since the tank stays closed, all of the propane gas stays inside the tank.

What will happen to the mass of the tank? EXPLAIN your answer.
