If a cylinder (system) containing pure liquid A and pure gaseous A in equilibrium
with the external pressure of 1 atm at the temperature T is brought to a new
condition where the temperature is Tl and the pressure is 1 atm, what change would
occur to the system?
If the gaseous phase in the cylinder is initially not the pure A, but a mixture of A
and an inert gas, what would be the pressure of A in the gas phase at the new
condition?
