In Joly's defferential steam calorimeter, 3 g of an ideal gas is contained in a rigid closed sphere at 20∘C. The sphere is heated by steam at 100∘C and it is found that an extra 0.095 g of steam has condensed into water as the temperature of the gas becomes constant. Calucate the specific heat capacity of the gas in J g−1 K−1. The latent heat of vaporization of water = 540 cal g−1 |
