If the pressure of an ideal gas is decreased by 10 % isothermally, then its volume will
Options
- Adecrease by 8 %
- Bdecrease by 9 %
- Cincrease by 8 %
- Dincrease by 11 %
Correct answer
D. increase by 11 %
Step-by-step solution
For isothermal process, P ₁ ~V ₁= P ₂ ~V ₂ aligned & P ₂= P ₁- P ₁ 10 = 9 10 P ₁ & P ₁ ~V ₁= 9 10 P ₁ ~V ₂ & V ₂= 10 9 ~V ₁ & =1.11 ~V ₁ & = V ₁+0.11 ~V ₁ aligned Volume increase by 11 %
