QJEEM20Ph82f0: JEE Main 2020 Physics - Class 11 JEEM20Ph82f0 Solution: Three different processes that can occur in an ideal monoatomic …
Three different processes that can occur in an ideal monoatomic gas are shown in the P vs V diagram. The paths are labelled as A B, A C and A D. The change in internal energies during these process are taken as EAB, EAC and EAD and the work done as WAB, WAC and WAD.
The correct relation between these parameters are :
The correct relation between these parameters are :
Multiple Choice Options
- A EAB < EAC < EAD, WAB > 0, WAC > WAD
- B EAB = EAC = EAD, WAB > 0, WAC = 0, WAD < 0
- C EAB > EAC > EAD, WAB < WAC < WAD
- D EAB = EAC < EAD, WAB > 0, WAC = 0, WAD < 0
Step-by-Step Verified Solution
For all process,
EAB = EAC = EAD
WAB > 0 as volume increases.
WAC = 0 as volume constant.
WAD < 0 as volume decreases.
EAB = EAC = EAD
WAB > 0 as volume increases.
WAC = 0 as volume constant.
WAD < 0 as volume decreases.
