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° C. The gas is
(R = 8.3 J mol−1 K−1 )
-
monoatomic
-
diatomic
-
triatomic
-
a mixture of monoatomic and diatomic
Solution
B.
diatomic
146 = Cv∆T
⇒ Cv = 21 J/mol K
