A certain mass of a gas occupies a volume of 2 dm ³ at STP. At what temperature the volume of gas becomes double, keeping the pressure constant?

Options

  1. A540.15^ C
  2. B400.15^ C
  3. C546 15^ C
  4. D273.15^ C

Correct answer

D. 273.15^ C

Step-by-step solution

array l V ₁=2 dm ³, ~T ₁=273.15 ~K ~V ₂=4 dm ³, ~T ₂=? array According to Charle's law, array l V₁ T₁ = V₂ T₂ T₂= V₂ T₁ V₁ T₂= 4 273.15 2 =546.3 ~K array Now, T k = t ^ C +273.15 t ^ C = T k -273.15 t ^ C =546.3-273.15=273.15^ C
