Question

Inter-particle space is maximum in

• A. Solid
• B. Liquid
• C. Gases
• D. All the above

Answer 1

The correct option is C

Gases

The explanation for the correct option:

Option(C) Gases:

Gases have neither a fixed shape nor a fixed volume.

Characteristic:

1. .They do not have fixed boundaries. They can flow in all directions and can be easily compressed.
2. In a given space, the number of particles in gases are less than that in solids and liquids.
3. The constituent particles of gases have maximum kinetic energy.
4. Gases show a random motion by moving in all directions due to high kinetice energy.
5. Gases have maximum movement of particles since they have maximum space between them. Thus, inter-particle space is maximum is gases.

The explanation for the incorrect option:

Option(B)-Liquid:

Liquid has more inter-particle attraction than gases, but less than solids, so they are close to each other.

Option(A)-Solid:

Solid has minimum space between particles because of the strong force of attraction.

Final Answer: . Inter-particle space is maximum in Gases-option(C).
