A diatomic gas (γ = 1.4) does 200 J of work when it is expanded isobarically. Find the heat given to the gas in the process
500 J
700 J
600 J
900 J
B.
700 J
For a diatomic gas
CV = and CP =
The work done in an isobaric process is
W = P ( V2 - V1 )
= n R ( T2 - T1 )
⇒ T2 - T1 =
The heat given in an isobaric process is
Q = n CP (T2 - T1 )
⇒ =
⇒ n CP = 700 J
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 )
