Question

Which one can be compressed by applying pressure?

• A. Solid
• B. Liquid
• C. Gas
• D. All of these

Answer 1

The correct option is C

Gas

Gases: A gas is a state of matter, which has a definite mass, but no definite shape and no definite volume.

Properties :

• A gas contained in a vessel has a definite mass.
• Gases do not have definite shape and volume.
• Gases are highly compressible because intermolecular spaces between them are very-very large as compared to solids and liquids.
• The density of gases is extremely small as compared to solids and liquids.
• Intermolecular forces are negligible.
• Gases expand to a large extent when heated.
• Gases diffuse in one another rapidly to form a homogeneous mixture.

Solids have negligible compressibility.

Liquids are slightly more compressible than that solids.

Gases are highly compressible because intermolecular spaces between them are very-very large as compared to solids and liquids.

Hence, (C) is the correct option.
