Question

Arrange the following in the increasing order of force of attraction:iron nail,kerosene and okygen gas.

Answer 1

Before we answer, let us know something :-

» Gases have least force of attraction between their particles.

» Liquids have moderate force of attraction between their particles.

» Solids have highest force of attraction between their particles.

» Oxygen is a gas. Kerosene is a liquid and iron nail is a solid.

Hence, the order of increasing force of attraction between their particles is :-

Oxygen < Kerosene < Iron nail.

Hope it helps dear friend ☺️✌️✌️

Answer 2

▶▶▶▶(a) (i) Force of attraction : Oxygen gas < Kerosene < Iron nail

▶▶▶▶(ii) Intermolecular space : Iron nail < Kerosene < 02
gas

▶▶▶▶(b) (i) Rigidity : It is property of matter to maintain shape
against external force.

▶▶▶▶(ii) Compressibility : It is the property of matter by virtue of
which molecules of matter are brought closer to each other.

▶▶▶▶(iii)Diffusion : The inter mixing of the particles of matter is known as diffusion.
