Question

Give three characteristics each of a solid, liquid, and gas.

Answer 1

Solids:
(i) Solids are rigid, do not flow and are incompressible.
(ii) A solid keeps its shape unless a force is applied to it. It has a definite volume.
(iii) The particles of a solid are in a fixed position and are very close to one other.

Liquids:
(i) Liquids are almost incompressible but less incompressible than solids.
(ii) Liquids have a fixed volume but no fixed shape.
(iii) The particles of a liquid are not in a fixed position and are a little further apart than the particles of a solid. Thus, the particles of a liquid are free to slide and flow.

Gases:
(i) Gases can be compressed easily by applying pressure.
(ii) Gases have no fixed volume or shape.
(iii) Gases can diffuse into each other rapidly.
