'Exercise #3
A container is filled with moles of a diatomic ideal gas. Initially, the gas is in a thermo dynamic equilibrium state A and has volume VA: By following 3 reversible thermodynamic process described by the law P(V) a V, where a is a positive constant; the gas reaches 3 new thermodynamic equilibrium state B, in which its volume is quadrupled_ All the quantities mentioned so far are assumed to be known. Find: 3) The values of the thermodynamic variables (P. V T) in the states A and B'
