Question

The molar specific heat of nitrogen at constant volume is 4.952 cal/mol.K and that at constant pressure is 6.933 cal/mol.K. Find the mechanical equivalent of heat. Take R = 8.31 J/mol.K.

Answer 1

Data : C_v = 4.952 cal/mol.K, C_p = 6.933 cal/mol.K, R = 8.31 J/mol.K

C_P - C_V = \(\frac RJ\)

\(\therefore\) The mechanical equivalent of heat,
