Concept:Solids have tightly packed particles with very little empty space, making them practically incompressible.
Explanation:In a solid, particles are arranged in a regular, orderly pattern and are held together by strong intermolecular forces.
These particles have almost no free space between them.
When pressure is applied, the particles cannot move closer together, so the volume of the solid does not decrease noticeably.
This is why solids cannot be easily compressed.
Other options are incorrect: liquid particles are less orderly than solid particles, most solids are denser than liquids, and particles in a liquid have greater kinetic energy than those in a solid.
Answer:D. Solid particles cannot be easily compressed
