MHT CET 2024 Physics question
Initial pressure and volume of a gas are 'P' and 'V' respectively. First its volume is expanded to '4V' by isothermal process and then again its volume is reduced to 'V' by adiabatic process then its final pressure if
Answer: (2)
Solution
Step 1 (isothermal, = constant): . Step 2 (adiabatic compression from to , = constant): $^γ = V^γ ⇒ = · 4^γ =
