Question

Which of the following best describes gases?

• A. No definite volume and no definite shape
• B. Definite shape and volume
• C. Definite volume but no definite shape
• D. Definite shape but no definite volume

Answer 1

The correct option is A No definite volume and no definite shape

Among the three states of matter, gases have the minimum interparticle force of attraction and thus the maximum interparticle space. Hence, they spread out to fill the entire volume of the container.

Thus, gases neither have a definite shape nor a definite volume.

Gases can be compressed or expanded easily as compared to any other state of matter because of the presence of void space between the gas molecules/ atoms.
