A cyclic process is shown in the `P-T` siagram. Whech of the curves show the same process on a `P-V` diagram ?

Options

A.
B.
C.
D.

Answer

B

Explanation

`(PV)/(T)=` constant (for given mass of ideal gas)
AB: isochoric process, V: constant T is increasing hence, P is increasing
BC: isobaric process, P: constant, T is decreasing hence, V is decreasing.
CA: isothermal process, P is decreasing hence, V is increasing, `P-V` diagram, P is decreasing hence, V is increasing, `P-V` diagram is rectangular hyperbola.
