उत्तर

For two states to be connected by an isothermal process,

P1V1 = P2V2 ... (i)

For the same two states to be connected by an adiabatic process,

P1V1γ  = P2V2γ ...(ii)

If both the equations hold simultaneously then, on dividing eqaution (ii) by (i) we get

V1γ-1 = V2γ-1

Let the gas be monatomic. Then,

γ =`5/3`

`=> "V"_1^ (2/3)= "V"_2^(2/3)`

⇒ V1 = V2

If this condition is met, then the two states can be connected by an isothermal as well as an adiabatic process.
