The work of 146 kJ is performed in order to compress one kilomole of a gas adiabatically and in this process the temperature of the gas increases by 7°C. The gas is
detailed solution
Correct option is A
For adibatic process, dQ = 0 i.e., dU = -dW∴ nCVdT=146×103JIf the the degrees of freedom, thennfR2×7=146×103 ∴ 103×f×8⋅3×72=146×103Solving, we get f=5⋅02≈5So, the gas is diatomic,Talk to our academic expert!
