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 ?
A
4
B
3
C
2
D
1
Answer
2
Explanation
Solution
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.
