The ideal gas of mass m in a state A goes to another state B via three different processes as shown in figure. If Q1, Q2 and Q3 denote the heat absorbed by the gas along the three paths, then –
A
Q1< Q2< Q3
B
Q1< Q2 = Q3
C
Q1 = Q2> Q3
D
Q1> Q2> Q3
Answer
Q1< Q2< Q3
Explanation
Solution
Initial and final states are same in all the
process. Hence DU = 0; in each case.
By FLOT; DQ = DW = Area enclosed by curve with volume axis.
\Area)1 < (Area)2 < (Area)3 ̃ Q1 < Q2 < Q3.
