Question

A small quantity of gas is let into a large evacuated chamber. i) How much of the chamber gets filled with the gas? ii) What property of the gas helps it to do so?

Answer 1

The chamber is filled uniformly. This would be the case even if the chamber were not evacuated........

Explanation:

`"Dalton's Law of Partial Pressures"` holds that in a gaseous mixture, the partial pressure exerted by a component gas is the same as the pressure it would exert if it alone occupied the container. This is the experimental result: the gas expands to fill the entire chamber.
