Question

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

Answer 1

Hint: Matter is any substance which has some mass, volume and take some space. Matter has three states known by the name solid, liquid and gas. These can be distinguished on the basis of intermolecular forces, arrangement of molecules.

Complete answer:
Solid substances are those in which molecules are attached very tightly with each other i.e. the intermolecular forces between them is very strong due to which they have fixed shape. In case of liquids the intermolecular forces between them is lesser as compared to solid but stronger as compared to gaseous particles and in case of liquids they have tendency to flow. In gaseous particles the forces are very less so that they have a great tendency to flow.
On the basis of above definition we can conclude that the intermolecular forces of attraction between the particles present in gas is very so
i) The whole chamber gets filled with gas as molecules of gases have greater tendency to flow.
ii) The tendency of flow of particles due to very less intermolecular forces will help it to do so.

Note: Solid state has definite shape, liquid state takes the shape of container in which it is kept and gaseous state has no shape as it has a great tendency to flow. Intermolecular forces are those forces which binds the molecules of matter together.
