1 Suppose 120 g of water gas is compressed isothermally at 6000C from 10 L to 2 mL. Calculate the heat and work done by the system, the change in internal energy, and the change in entropy if:
a) the process is via a reversible path (sketch the pathway) b) the process is non-reversible (sketch the pathway) c) which pathway will require the least work and why? (10 marks)
