Question

Which of the following characteristics is associated with a gaseous state?

• A. fixed shape, incompressible, packed closely
• B. incompressible, fixed shape and size
• C. definite shape, compressible and fixed volume
• D. no fixed shape and size, highly compressible

Answer 1

The correct option is D

no fixed shape and size, highly compressible

Explanation for correct option:

D. no fixed shape and size, highly compressible

Gas:

• The intermolecular forces between gaseous particles are negligible.
• Gas has no definite volume or shape.
• Examples are oxygen as well as carbon dioxide.

Characteristics of gaseous state:

• Gases are fluid and can flow easily.
• The particles in gases are very loosely packed.
• Gases have neither definite shape nor definite volume.
• The density of gases is very low.
• Gases can be compressed or expanded easily.

Hence, the correct option is D i.e. no fixed shape and size, highly compressible.
