A vessel containing 1 more of O ₂ gas (molar mass 32) at temperature T . The pressure of the gas is p. An identical vessel containing one mole of he gas (molar mass 4 ) at temperature 2 ~T has a pressure of

Options

  1. Ap / 8
  2. Bp
  3. C2 p
  4. D8 p

Correct answer

C. 2 p

Step-by-step solution

Applying gas equation, pV = nRT We can write, p ₁ ~V = n ₁ RT ₁ and p ₂ ~V = n ₂ RT ₂ p ₂ p ₁ = n ₂ n ₁ T ₂ ~T ₁ = 1 1 2 ~T ~T =2 p ₂=2 p
