Question

Which of the following is/are property/properties of gas?

• A. Compressibility
• B. Rigidity
• C. Fluidity
• D. Definite shape

Answer 1

Answer: (A), (C)

The correct options are
A

Compressibility

C

Fluidity

Compressibility is one of the most important characteristic of the gas. Because of the large intermolecular space between particles, a gas can be compressed to a great extent. Liquid and solid cannot be compressed because of lesser space between their particles. The ability to flow is called fluidity. The less force of attraction and large space between particles make liquid and gas to flow. That’s why liquid and gas are called fluids. Therefore, gases do not have a definite shape or volume.
