Two identical gases of the noble gas group with the same pressure P and the same number of particles N = 1024, but with different temperature T1 = 300K and T2 = 600K, are conned in two vessels of volume V1 and V2, which are then connected. Find the change in entropy after the system has reached equilibrium.
