(i) Rigidity: The tendency of a substance to retain/maintain their shape when subjected to outside force. (ii) Compressibility: The matter has intermolecular space. The external force applied on the matter can bring these particles closer. This property is called compressibility. Gases and liquids are compressible. (iii) Fluidity: The tendency of particles to flow is called fluidity. Liquids and gases flow. (iv) Filling of a gas container: Gases have particles which vibrate randomly in all the directions. The gas can fill the container. (v) Shape: Solids have maximum intermolecular force and definite shape.
Whereas liquids and gases takes the shape of container. (vi) Kinetic energy: The energy possessed by particles due to their motion is called kinetic energy. Molecules of gases vibrate randomly as they have maximum kinetic energy. (vii) Density: It is defined as mass per unit volume, the solids have highest density.
The characteristics of the particles of matter are: (1) Particles have intermolecular space. (2) Particles have intermolecular force. (3) Particles of matter are moving continuously.

A diver is able to cut through water in a swimming pool. This shows that the particles of water have intermolecular space and has less force of attraction.

The smell of hot sizzling food reaches severed meters away, as the particles of hot food have more kinetic energy and hence the rate of diffusion is more than the particles of cold food.

(vii) Density: It is defined as mass per unit volume, the solids have highest density.
The mass per unit volume of a substance is called density. (density = mass/volume). Arrange the following in order of increasing density-
Increasing density: air < exhaust from chimneys < cotton < water < honey < chalk < iron.
