Question

The work of 146 kJ is performed in order to compress one kilomole of a gas adiabatically and in this process the temperature of the gas increase by 7 ° C . The gas is R = 8 .3 J mol - 1 K - 1, Diatomic, Triatomic, A mixture of monoatomic and diatomic, None of the above

MARKS App · Accepted Answer

For the adiabatic process, d Q = 0 ⇒ d U = - ∆ W Or n C v d T = + 146 × 10 3 J ⇒ n f R 2 × 7 = 146 × 10 3 J Where, f is the degree of freedom ⇒ 10 3 × f × 8.3 × 7 2 = 146 × 10 3 J f = 5.02 ≃ 5 Therefore, gas is diatomic.
