Structure of solid and liquid

  1. Feb 16, 2014 #1
    Atoms in solid are more closedly packed as compared to liquid and gases. But we exert more force, some solid gets compressed but liquid doesn't, why? If atoms are loosely packed in liquid than solids, liquids should get compressed.......

    Can you give an example of a solid which gets compressed?

    The OP is confusing an idealization (incompressible liquids) with reality. Real liquids do compress. Nevertheless, the idealization is very useful to solve problems. BTW, liquids are not necessarily more loosely packed than solids. Water, for instance, is more dense than ice (at standard pressure).

    Every solid and every liquid compresses with pressure, except for unobtainium of course. As it takes a good deal of pressure to result in even a very small change in density, treating solids and liquids as incompressible is a good first order approximation.

    I didn't mean solids can't be compressed.I was asking in common terms(everyday life).
