JEE MAIN - Physics (2020 - 5th September Morning Slot - No. 4)
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 $$ \to $$ B,
A $$ \to $$ C and A $$ \to $$ 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 :_5th_September_Morning_Slot_en_4_1.png)
The correct relation between these parameters are :
EAB < EAC < EAD, WAB > 0, WAC > WAD
EAB = EAC = EAD, WAB > 0, WAC = 0, WAD < 0
EAB > EAC > EAD, WAB < WAC < WAD
EAB = EAC < EAD, WAB > 0, WAC = 0, WAD < 0
Explanation
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.
