A cyclic process ABCD is shown in the p-V diagram. Which of the following curves represent the same process?

Options

A.
B.
C.
D.

Answer

A

Explanation

AB Isobaric process. Both volume and temperature are increasing.
BC Isomthermal process. Volume is increasing. So, pressure should decrease. (T= constant, `pprop1/V`)
CD Isochoric process. Pressure and temperature both are diecreassing, (V = constant, p `prop` T)
DA Again isothermal process. Volume is deceasing and pressure is increassing ( T = constant, `pprop1/V`)
