MHT CET 2024 Physics question
A diatomic ideal gas is used in Carnot engine as a working substance. If during the adiabatic expansion part of the cycle, the volume of the gas increases from v to 32 v, the efficiency of the engine is
Answer: (C)
Solution
For a diatomic gas . In the adiabatic expansion (from the source temperature to the sink temperature ) is constant: , so $ = ( =
