Question

Two identical Flasks each of volume V, are connected through a tube controlled by a stopcock.The material of which this apparatus is constructed is a perfect thermal insulator.Initially n moles of a monoatomic van der Walls gas are confined to one flask at temperature T0 and the other flask is empty.The stopcock is then opened and time is allowed for restoration of equilibrium.Assume that the gas has the same heat capacity as if it were ideal.Find q , w, change in U,T and S for this gas in terms of n, V,T0,R and the VDW constants a and b.

Explanation / Answer

initial conditions are P,V ,n ,To finally for the system to be stable the 2 vessels must be in same condition i.e each will have n/2 moles P/2 pressure by using the equation for vdw we can get the final temperatures of each flask hence we get the q w and change in u t and s
