Question

In which state does matter spread and fit into whole space available?

• A. Solid
• B. Liquid
• C. Gas
• D. All of the above

Answer 1

The correct option is C

Gas

Explanation for correct option:

(C) Gas:

• Gases have neither a definite shape nor a definite volume.
• Matter spread itself and fits into the whole space available in the gaseous state because in gases negligible or very less force of attraction is present among the particles hence they can move freely in all available space.

Explanation for incorrect option:

(A) Solid: Solids have strong intermolecular forces of attraction between their particles and less intermolecular space. Hence, matter cannot move freely in solid-state.

(B) Liquid: Liquids have fewer intermolecular forces of attraction as compared to solids and have more intermolecular space compared to solids. So, matter can spread but not as in the case of gases.

Therefore, the correct option is (C).
