1. The problem statement, all variables and given/known data For some particular unusual non-ideal monatomic gas, take the relation beween P and V at some fixed To to be P = Po(Vo/V)1/2. Let To = 100 K, Po = 100000 Pa, and Vo = 0.1 m3. 2. Relevant equations How much work does this gas do if it expands, pushing on a piston, from Vi = 0.3 m3 to Vf = 0.44 m3 at T = 100 K? 3. The attempt at a solution Someone please help!?! I don't understand non-ideal gases.
