4.00 Litres of hydraulic oil is placed in a cylinder with a movable piston, on which a heavy block is placed. The hydraulic oil pressure is maintained at 2.45x105 Pa and the temperature of the oil is raised by 45K. The oil is in liquid phase and expands by a small amount of 1.2x10-3m3. Calculate the work done on the oil and the change in internal energy of the oil. The specific heat capacity of hydraulic oil is 2300J/(kg•K) and its density is 800kg/m3
