Question

use particle theory to explain why solids and liquids cannot be compressed

Answer 1

According to the Kinetic particle theory:
Liquids and gases cannot be compressed easily : the particles are close together or touching. increasing the pressure has little effect since the particle theory assumes that the particles are " hard"

Answer 2

Answer:

Compressibility is the measure of how much a given volume of matter decreases when placed under pressure. If we put pressure on a solid or a liquid, there is essentially no change in volume. The atoms, ions, or molecules that make up the solid or liquid are very close together.
