An ideal gas undergoes for different processes from the same initial state (figure). 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

Text Solution

Verified by Experts

The correct Answer is:
C
In curve 1, V is constant : It represents isochoric process. In curve 4, P is constant. It represents isobaric process. Out of curves 2 & 3, one is isothermal and other is adiabatic process. As slope of curve 2 is more than the slope of 3, therefore. Curve 2 represents adiabatic process.
