1.	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
Answer» SOLUTION :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.
