An ideal gas undergoes four different processes from the same initial state as shown in figure of P-V diagram. Four processes are adiabatic, isothermal, isobaric and isochoric. Out of 1,2,3 and 4 which one is adiabatic ?

1.	An ideal gas undergoes four different processes from the same initial state as shown in figure of P-V diagram. Four processes are adiabatic, isothermal, isobaric and isochoric. Out of 1,2,3 and 4 which one is adiabatic ?
Answer» 4 3 2 1 Solution :For the CURVE 1 is parallel to pressure axis. So, VOLUME is CONSTANT. So, this is isochoric process. Out of CURVES 2 and 3, curve 2 is sleeper so it is adiabatic and curve 3 is isothermal and curve 4 is parallel to volume axis. So, pressure is constant so this is an isobaric process.
