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 7oC. The gas is
(R = 8.3 J mol-1 K-1)
(R = 8.3 J mol-1 K-1)
Options
A.monoatomic
B.diatomic
C.triatomic
D.a mixture of monoatomic and diatomic
Solution
146 = CvᐃT
⇒ Cv = 21 J/mol K
⇒ Cv = 21 J/mol K
Cv of diatomic gas is 20.8 J/mol K
