Answer» Given info : Volume of 100 liter gas increases to 120 liter at constant temperature and 10 bar external pressure. To find : The workdone by the system is .. solution : work done at constant temperature is given by, W = P∆V here Pressure , P = 10 bar and change in volume , ∆V = V₂ - V₁ = 120 litres - 100 litres = 20 litres. now workdone by the system = 10 bar × 20 litres = 200 litre bar but given, I litres bar = 24.21 cal = 200 × 24.21 cal = 4842 cal Therefore the workdone by the system is 4842 cal. also read similar questions : A gas at a volume of 4 LITERS is at a pressure of 2 atm.
