Initial pressure and volume of a gas are ' P ' and ' V ' respectively. First its volume is expanded to ' 4 V ' by isothermal process and then again its volume is reduced to ' V ' by adiabatic process then its final pressure if ( = 3 2 )
Options
- AP
- B2 P
- C3 P
- D4 P
Correct answer
B. 2 P
Step-by-step solution
After isothermal expansion, aligned & P₁ V₁=P₂ V₂ & P V=P₂ 4 V & P₂= P 4 aligned After adiabatic compression, array lll & P₂ V₂^ =P₃ V₃^ & & P 4 (4 V)^ =P₃(V)^ & ( given V₃= V ) & P₃= P 4 4^ = P 4 4^ 3 / 2 & ( given , = 3 2 ) & P₃= P 4 8=2 P & array
