Explanation:
The initial state of one mole of a monoatomic ideal gas is P= 10 atm and T = 300 K. Calculate the change in the entropy of the gas for
(a) An isothermald ecrease in pressure to 5 atm
(b) A reversible adiabatic expansion to a pressure of 5atm
R = 0.082057 L.atm/ mole.K = 8.314 J/ mole.K
= 8.314 kJ/kmole.K
