A cloud bank moving across the ocean at an altitude of 2000m encounters a coastal mountain range. As it rises to a height of 3500m to pass over the mountains, it undergoes an adiabatic expansion. The pressure at 2000 and 3500m is 0.802 atm and 0.602 atm respectively. If the initial temperature of the cloud is 288 K, what is the cloud temperature as it passes over the mountains? (Do you expect rain or snow?) Assume Cp = 28.86 J/K/mol for air. Clearly state any assumptions.
