Question

${\mathrm{CO}}_2$ can be easily liquified and even solidified because:

• A. It has a weak force of attraction
• B. It has comparatively more force of attraction than other gases
• C. It has more inter-molecular space
• D. It is present in the atmosphere

Answer 1

The correct option is A

It has a weak force of attraction

Explanation:

• Carbon dioxide ${\mathrm{CO}}_2$ is a gas and has a weak intermolecular force of attraction between its molecules.
• It can be easily solidified and even liquified because it has a low melting point and low boiling point.
• Carbon dioxide at very low temperature and pressure can change from an excited state to a stable state and vice versa.

Hence, option A is the correct answer. ${\mathrm{CO}}_2$ can be easily liquified and even solidified it has a weak force of attraction.
