Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): With the increase in the pressure of an ideal gas, the volume falls off more rapidly in an isothermal process in comparison to the adiabatic process.
Reason (R): In an isothermal process,
PV=constant, while in an adiabatic process
PVγ=constant. Here,
γ is the ratio of specific heats,
P is the pressure and
V is the volume of the ideal gas.
In the light of the above statements, choose the correct answer from the options given below:
