Verified Answer
A cyclic process ABCA shown in the V-T diagram is performed with a con...
Process A → B
From the graph,  
From ideal gas equation, pV = nRT
⇒ p = constant
⇒ A → B, is isobaric process
So, in process A → B, when volume increases, pressure remains constant.
So, pV graph will be straight line parallel to V–axis as p = constant
Process B → C
From the graph, V = constant
From ideal gas equation, pV = nRT
⇒ pV = nRT
 [V is constant]

But from the graph T is decreasing, so p also decrease.
But V remain constant.
pV graph will be straight line parallel to p-axis as V = constant
Process C → A
From the graph,
T = constant
From ideal gas equation, pV = nRT
⇒pV = nRT [T is constant]

But from the graph, V decreases, so p should increase.
so, pV graph will be rectangular hyperbola as
