The gas goes from\[I\]to F by (i) \[IAF\] (ii) \[IBF\] (iii) \[ICF\] The heat absorbed by gas is
A) the same in all three processes
B) the same in (i) and (ii)
C) greater in (i) than in (ii)
D) the same in (i) and (iii)
E) greater in (iii) than in (i)
Correct Answer: C
Solution :
Initial and final states are same in all the processes hence\[\Delta U=0\]in each case By flot\[\Delta Q=\Delta W\]Area enclosed by curve with volume axis \[\because \] \[{{(Area)}_{1}}>{{(Area)}_{2}}<{{(Area)}_{3}}\] \[={{Q}_{1}}>{{Q}_{2}}<{{Q}_{3}}\]
