5 moles of Nitrogen gas are enclosed in an adiabatic cylindrical vessel. The piston itself (which is free to move vertically) is a rigid, light cylindrical container, containing 3 moles of Helium gas, is placed over Nitrogen. There is a heater which gives out a power of 100 cal/s to the Nitrogen. A power of 30 cal/s is transferred to Helium through the bottom surface of the piston. The rate of increment of temperature of the nitrogen gas in K/s is (assuming that the piston moves slowly and R=2 calmol.K) (Answer upto two digits after the decimal) |
