2020 Phase-2 ThermodynamicsThermodynamic processes - P-V diagrams Medium Question 13 of 54 in Thermodynamics

The P-V diagram for an ideal gas in a piston cylinder assembly undergoing a thermodynamic process is shown in the figure. The process is

A isothermal
B adiabatic
C isochoric
D isobaric

The answer is D.

Solution

A horizontal line on a P-V diagram represents a process at constant pressure, i.e. an isobaric process.
