Question

Expansion is maximum in

• A. Solids
• B. Liquids
• C. Gases
• D. Both (A) and (B)

Answer 1

The correct option is C

Gases

Explanation for the correct option is

Option C: Gases

1. The particles are loosely bound. They don't have a fixed shape or volume
2. Thus, upon heating the particles move further away from each other exhibiting a large amount of cubical expansion.

The explanation for incorrect answers are:

Option A: Solids

1. The particles are tightly bound. They have a fixed shape and volume.
2. Because of the tight binding, the particles do not move away from each other easily.

Option B: Liquids

1. The particles are loosely bound compared to solids but a bit tightly bound compared to gases.
2. They do not have a fixed shape but they have a fixed volume. They take the shape of the container they are put in.
3. Because of the loose binding the particles do move away from each other but not as much as observed in gases.

Hence the correct option is option (C).
