Question

The specific heat capacities of hydrogen at constant volume and at constant pressure 2.4 cal g1 0C1 and 3.4calg1 0C1 respectively. The molecular weight of hydrogen is 2 g mol1 and the gas constant R=8.3×10γ ~erg0C1mol1. Calculate the valuve of J

Solution

Cv(H2)=2.4 cal,/g C,

Cp(H2)=3.4 cal,/g C

M = 2 g/mol.

R = 8.3 ×107erg/mol.C

We know, CpCv = 1 cal/g C

So, difference of molar specific heat,

Cp×MCv×M=1 cal/gC

Now, 2×J=R

2×J=8.3×107 erg/mol.C

J=4.15×107 erg/cal.
