Question

One of the characteristic properties of gases is that:

• A. Gases are not at all rigid
• B. Gases are not compressible
• C. Gases have particles in fixed positions
• D. Gases have high density

Answer 1

The correct option is A

Gases are not at all rigid

The explanation for the correct option: Option A

• The particles of gases do not have a fixed shape because the particles are loosely packed and therefore they are not rigid at all.

The explanation for the incorrect option:

• Option B: The particles of gases are easily compressible because there are only a few particles in a large volume.
• Option C: The force of attraction between the gaseous particles is almost negligible and they have high kinetic energy and therefore, they move randomly in all directions.
• Option D: The gaseous particles often possess a low density as there are few particles in a large space.

Therefore, Option A is correct.
