Question

What are the classifications of matter based on physical nature?

Answer 1

Matter:

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

Classification of the matter:

Matter can be classified in two ways:

• On the basis of physical nature
• On the basis of its chemical nature

A matter can be categorized into three categories on the basis of physical nature:

Solid:

• The particles in a solid are tightly packed due to the strong intermolecular attractions.
• A solid has a definite shape, volume, and mass.
• Examples of solid are books, iron, and wood.

Liquid:

• The intermolecular attractions in liquids are weaker than in solids, thus the particles are allowed to move around freely.
• A liquid has a fixed volume but its shape is not fixed, it usually takes the shape of a container.
• Examples of liquids are water and alcohol.

Gas:

• The intermolecular forces between gaseous particles are negligible.
• A gas has no fixed volume or shape.
• Examples of gases are Oxygen and carbon dioxide.
