The pressure of an ideal gas undergoing isothermal change is increased by 10 % . The volume of the gas must decrease by about

Options

  1. A0.1 %
  2. B9 %
  3. C10 %
  4. D0.9 %

Correct answer

C. 10 %

Step-by-step solution

In isothermal process aligned & T =0 & P V= Constant & P 1 ~V aligned From P ₁ ~V ₁= P ₂ ~V ₂ here P ₂= (1+ 10 100 ) P ₁=1.1 P ₁ Change in volume V₁-V₂ V₁ = 1 11 Percentage decrease =9.09 % .
