One mole of an ideal gas is allowed to expand reversible and adiabatically from a temperatureof`27^(@)C)`if the work done during the process is`3`kJ,the final temperature will be equal to`(C_(v)=20JK^(-1))`A. ` 100 k `B. ` 450 k `C. ` 150 k `D. `400 k`

Answer» Correct Answer - C
`W = - n C_(v) (T_(2)-T_(1)) rArr T_(2) = 150 K`
