The amount of matter in an object is known as the mass. The S.I unit of mass is Kilogram.

Solids have fixed shape, size and volume because the molecules in solid are closely packed and in fixed positions.

Matter can change from one state to another when thermal energy is absorbed or released i.e. when temperature changes.

Sugar is an example of a solid, whereas water is an example of a liquid.

Condensation is the process where water vapor becomes liquid by taking heat away from the matter.

The particles in solids are closely packed together.
