`5` moles of nitrogen gas are enclosed in an adiabatic cylindrical vessel. Thel piston itself is a rigid light cylindrical container containing `3` moles of helium gas. There is a heater which given out a power of `30` cal is transferred to helium through the batton surface of the piston. The rate of incremnt of temperature of the nitrogen gas assuming that the piston moves slowly, is
