Question

why liquids are slightly compressible​

Answer 1

Answer:

Liquids are compressible, otherwise shock and sound waves would not exist! In fact, it is a matter of ratio of density change to mean density - or more precise: convective velocity to speed of sound (which is the Mach number) to distinguish between compressible, slightly compressible and incompressible.

Answer 2

Explanation:

Molecules in the solid are tightly packed, so they r nt able to compress. In liquid, molecules are losely packed as compared to solid so they r slightly compressible and in gasses, molecules freely packed, they r highly compressible
