Question

For an ideal gas graph is shown for three processes. Process 1, 2 and 3 are respectively

• A. Isobaric, adiabatic, isochoric
• B. Adiabatic, isobaric, isochoric
• C. Isochoric, adiabatic, isobaric
• D. Isochoric, isobaric, adiabatic

Answer 1

The correct option is D Isochoric, isobaric, adiabatic

Isochoric process $dV=0$
$W=0$
process 1
Isobaric : $W=P\Delta V=nR\Delta T$
Adiabatic $W=\frac{nR\Delta T}{\gamma -1}:0<\gamma -1<1$
As workdone in case of adiabatic process is more so process 3 is adiabatic and process 2 is isobaric
