An ideal gas undergoes four different processes from the same initial state as shown in the figure below. Those processes are adiabatic, isothermal, isobaric and isochoric. The curve which represents the adiabatic process among 1,2,3 and 4 is.
2
3
4
1
curve 4 pressure is const constant, therefore it is an Isobaric process
curve 2 is more steeper than Curve 3
curve 2 Adiabatic
curve 3 Isothermal
For curve 1, volume is constant
curve 1 Isochoric process.
The correct option is (1)
