Question

What are the physical states of matter?

Answer 1

Matter:

• A matter is composed of tiny particles.
• Anything that has mass and takes up space is known as matter.

The matter is classified into three physical states that are discussed below:

Solid:

• In solid, the particles are tightly packed due to the strong intermolecular attractions.
• A solid has a definite shape, volume, and mass.
• Examples are books as well as wood.

Liquid:

• In liquid, the intermolecular forces are weaker than that of solids.
• Liquid has a definite volume but the shape of the liquid is not fixed. It usually takes the shape of a container.
• Examples are alcohol as well as water.

Gas:

• The intermolecular forces between gaseous particles are negligible.
• Gas has no definite volume or shape.
• Examples are oxygen as well as carbon dioxide.
