Question

Why gases are compressible but not liquids?

Answer 1

This is owe to the intermolecular space in between. The inter molecular space in between the constituent particles is maximum in gases, little less in the liquids and the least in solids. On applying pressure, the gaseous particles come together, where as in liquids and solids, the particles are very close and hence cannot be further brought closer. Hence gases are compressible but not liquids.
hope this helps..

Answer 2

its becoz of intermolecular force
