A balloon filled with oxygen is placed in a tank full of hydrogen gas at the same pressure, is pricked with a sharp pointed needle. The volume of balloon just after the pricking would be

Options

  1. AShrunk
  2. BEnlarge
  3. CCompletely collapsed
  4. Dremains unchanged in size

Correct answer

B. Enlarge

Step-by-step solution

According to graham's law of rate of diffusion, the rate of diffusion depends on pressure and molecular weight of the gas. Rate of diffusion ∝ partial pressure ∝ 1 M So According to graham's law of diffusion the rate of diffusion will be higher than the rate of diffusion of oxygen gas, So hydrogen gas will diffuse with a faster rate inside the balloon than oxygen gas will leave the balloon so balloon will enlarge in size.
