Answer
Solid is the phase of matter has strong intermolecular attractions that hold all the particles together in a fixed arrangement with a set shape and volume, with particles vibrating in that fixed position.
Step-by-step explanation
A solid can maintain its rigid shape because they have molecules that are tightly packed together. The particles are packed tightly together in a solid. The strong forces of attraction between the particles unable the particles to move freely. The kinetic energy of these particles is also very low. The electrons of all atoms are always in motion, so the atoms are always vibrating, but in solids, they have a very low kinetic energy that is why they are fixed in their position. Solid has a definite volume. The increasing pressure has no effect on the particles of a solid since are already so tightly packed together that it will not compress the solid to a smaller volume or expand the solid to a occupy a larger volume.
