An ideal gas undergoes four different processes from the same initial state as sown in P-V diagram. Four processes are adiabatic, isothermal, isobaric and isochoric.

Out of 1, 2, 3 and 4 which one is adiabatic?
Text Solution
Verified by ExpertsThe correct answer is:
C
1 is isochoric (constant volume), 4 is isobaric (constant pressure). Out or curves 2 and 3, curve
2 is steeper than curve 3, it represents an adiabatic change, whereas curved 3 represent an isothermal change.
