Question

help me solve the question which balloons will run out of gas first and why please give me the answer​

Answer 1

Answer:

Run out of a gas depends on the gas which diffuse first. The diffusion is indirectly proportional to square root of mass.

$d = c1 \div \sqrt[3]{m}$

In this following hydrogen gas is less mass so it will diffuse fast it will run out first.
