Question

In the given p-V diagram, I is the initial state and F is the final state. 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)

Initial and final states are same in all the processes hence Δ U=0 in each case By flot Δ Q=Δ W Area enclosed by curve with volume axis ∵ (Area)1>(Area)2<(Area)3 =Q1>Q2

Q. In the given $p - V$ diagram, I is the initial state and F is the final state.
The gas goes from $I$ to F by (i) $I A F$ (ii) $I BF$ (iii) $I CF$ The heat absorbed by gas is

the same in all three processes

the same in (i) and (ii)

greater in (i) than in (ii)

the same in (i) and (iii)

greater in (iii) than in (i)

Initial and final states are same in all the processes hence
$Δ U = 0$ in each case By flot
$Δ Q = Δ W$
Area enclosed by curve with volume axis
$∵$ $(A re a)_{1} > (A re a)_{2} < (A re a)_{3}$ $= Q_{1} > Q_{2} < Q_{3}$

Q. In the given p−V diagram, I is the initial state and F is the final state.The gas goes from I to F by (i) IAF (ii) IBF (iii) ICF The heat absorbed by gas is
