In an isobaric process of an ideal gas, the ratio of work done by the system to the heat supplied ( W Q ) is

Step-by-step solution

For an isobaric process, aligned & Q = nC _ p ~T and U = nC _ v ~T & ~W = Q - U = nC _ p ~T - nC _ v ~T aligned W Q = nC _ p T - nC _ v T nC _ p T = C _ p - C _ v C _ p = C_p C_v -1 C_p C_v W Q = -1 ( C_p C_v = )
