The work of 146 kJ is performed in order to compress one kilo mole of a gas adiabatically and in this process the temperature of the gas increases by 7^(@)C. The gas is (R 8 cdot 3J" mol"^(-1) K^(-1)): |

Answer» DIATOMIC `W=nC_(v)Delta T` `146xx10^(3)=10^(3)C_(v)xx7 rArr C_(v)=20 cdot 85 J" mol"^(-1)K^(-1)` This is same as `C_(v)` for diatomic gas `C_(v)=(5)/(2) R` Thus, CORRECT choice is (a). |
