Question
An ideal gas goes through a reversible cycle has the V - T diagram shown below. Process are adiabatic.
The corresponding P - V diagram for the process is (all figures are schematic and not drawn to scale) :
The corresponding P - V diagram for the process is (all figures are schematic and not drawn to scale) :
Choose an option
Show full solutionCorrect option: A
Correct answer
A
Step-by-step explanation
Is an adiabatic process
as T increase V decreases at non-uniform rate
In process P = constant as
In process constant s
But since slope of V - T graph
since slope of ab < slope of cd
Also in adiabatic process as T is increasing V in decreasing
P is increasing, so P - V diagram is as below
