Question
An ideal gas undergoes four 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.
Options
4
3
2
1
Solution
2
Explanation:
For curve 4 pressure is constant, so this is an isobaric process.
For curve 1, volume is constant, so it is an isochoric process. Between curves 3 and 2, curve 2 is steeper, so it is adiabatic and 3 is isothermal.
