Answer» Four students observed an ideal gas undergoing a change of state from A to B. Their observations are along four different paths shown in the figure below. Their conclusions are as follows: $(P)$ Change in internal energy is same in $I V$ and $I I I$ cases, but not in $I$ and $I I$ $(Q)$ Change in internal energy is same in all the four cases $(R)$ Work done is maximum in case $I$ $(S)$ Workdone is minimum in case $I I$ Which option represents correct conclusions drawn by the students?
