Question

What are examples of gases, liquids, and solids?

Answer 1

The matter is classified into three categories that are solid, liquid, and gas.

Solid

• In solids, the particles are tightly packed due to strong intermolecular attractions.
• Examples are wood, bricks, and gold.

Liquids

• In liquids, the forces of attraction are weaker than that of solids, thus the particles can move around freely.
• Examples are water, milk, and blood.

Gas

• In gases, there are negligible forces of attraction.
• Examples are oxygen $\left({\mathrm{O}}_2\right)$, carbon dioxide$\left({\mathrm{CO}}_2\right)$,and nitrogen$\left({\mathrm{N}}_2\right)$.
