The initial state of certain gas (P(i)V(...

The initial state of certain gas `(P_(i)V_(i)T_(i))`.It undergoes expansion till its volume becomes `V_(f)` at constant temperature T. The correct plot of P-V diagram for it is

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A
As PV =nRT
At constant temperature
`P_(i)V_(i)=nRT and P_(f)V_(f)=nRT rArr P_(i)V_(i) = P_(f)V_(f)`
In the given P-V diagram (a) at every point on the plot P-V is constant which shows a process at constant temperature i.e isothermal process.
