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 ?

An ideal gas undergoes for different processes from the same initial s

1.	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 ?
Answer» 4 3 2 1 Solution :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.
