Question

Which of the following statements are true about properties of gases?

• A. Gases have fixed shape
• B. Gases do not have fixed volume
• C. Gases are highly incompressible
• D. Gases have high rate of diffusion

Answer 1

Answer: (B), (D)

The correct options are
B Gases do not have fixed volume
D Gases have high rate of diffusion

Gases neither have a fixed shape nor fixed volume.
Gases have weak interparticle forces of attraction and large space between the particles. Due to this:
1. Gases are highly compressible.
2. The gas particles can move randomly from one place to another.
Thus, gases have a high rate of diffusion.
