Question

Helium is a gas used to fill balloons. It is present in air in very small quantities. Diffusion can be used to separate it from the air.
Air at 1000 degrees celsius is on one side of a porous barrier. The air which passes through the barrier has a larger amount of helium in it.
(i) Why does the air on the other side of the barrier contain more helium?
(ii) Why is it an advantage to have the air at a high temperature?

Answer 1

Answer:

Hi mate,

(I) The air on the other side of the barriers contain more helium because it is at a 1000 degrees.The air pressure is very high in that side.

(ii) The advantage to have air at high temperature because it reduces silly açcidents and it helps to fill balloons very attractively.
