A 1.00 mol sample of water vapour is enclosed in a rigid container equipped with a 9.97 Ω electric resistance heater. When a current of 0.200 A is passed through the resistor for 100.0 s, the temperature of the apparatus was observed to increase by 0.465 K. Separate measurements on the evacuated container show that the heat capacity of the container and resistance heater is 60.50 J. K-1. Calculate the value of Cv for the gaseous water (water vapour)
