Question
A gas is compressed from volume V1 to V.2 In which case work done will be more-isothermal compression or adiabatic compression?
Solution
The P-V curve for isothermal and adiabatic compression is as shown in figure.
We know that the area under PV graph is equal to work done on the gas.
Thus, the work done on gas during adiabatic compression is maximum and isobaric compression is minimum.
