Question 478: Thermodynamics & KTG

Question

The work of $146$ $kJ$ is performed in order to compress one kilo mole of gas adiabatically and in this process the temperature of the gas increases by ${7^ \circ }C.$ The gas is $\left( {R = 8.3J\,\,mo{l^{ - 1}}\,{K^{ - 1}}} \right)$

Accepted Answer

$W = {{nR\Delta T} \over {1 - \gamma }} \Rightarrow  - 146000$
$ = {{1000 	imes 8.3 	imes 7} \over {1 - \gamma }}$
or $1 - \gamma  =  - {{58.1} \over {146}} \Rightarrow \gamma $
$ = 1 + {{58.1} \over {146}} = 1.4$
Hence the gas is diatomic.

Answer
