A balloon contains 500 ~m ^3 of He at 27^ C and 1 atmospheric pressure. The volume of He at -3^ C and 0.5 atmospheric pressure will be

Options

  1. A700 ~m ^3
  2. B900 ~m ^3
  3. C1000 ~m ^3
  4. D500 ~m ^3

Correct answer

B. 900 ~m ^3

Step-by-step solution

Using standard gas equation, aligned p₁ V₁ T₁ & = p₂ V₂ T₂ or V₂= p₁ V₁ T₂ p₂ T₁ & V₂= 1 500 (273-3) 0.5 (273+27) & V₂= 1 500 270 0.5 300 & V₂=900 ~m ^3 aligned
