Question

Which of the following substances is most compressible co2 , h2o ,nacl

Answer 1

Answer:

Co2

Explanation:

Answer 2

ANSWER:

$\bold{\mathrm{CO}_{2}}$ or carbon dioxide is the 'most compressible gas'. The reason that carbon dioxide is most compressible is that it is a gas and gases are the most compressible of solids, liquids and gases.  

EXPLANATION:

Gases have the least inter-molecular spaces between their molecules and also the forces of attraction between molecules of gases are the least.

This makes gases easily compressible. Carbon dioxide being a gas can be easily compressed and stored in containers for use for several purposes.
