Correct Option (a) V1 = V2, V3 = V4 and V2 > V3
Explanation:
It means line of smaller slope represent greater volume of gas. For the given problem figure
Point 1 and 2 are on the same line so they will represent same volume i.e. V1= V2
Similarly point 3 and 4 are on the same line so they will represent same volume i.e. V3 =V4
But V1 > V3 (= V4 ) or V2 > V3 (= V4 ) as slope of line 1-2 is less than 3-4.
