EVERYDAY SCIENCE

Detailed explanation-1: -In a solid, particles are packed tightly together so they don’t move much. The electrons of each atom are constantly in motion, so the atoms have a small vibration, but they are fixed in their position. Because of this, particles in a solid have very low kinetic energy.

Detailed explanation-2: -In solids, the particles are tightly packed together. In liquids, the particles have more movement, while in gases, they are spread out. Particles in chemistry can be atoms, ions or molecules.

Detailed explanation-3: -Explanation: Solid is the state of matter with the most tightly packed particles/atoms vibrating about a fixed point; they have definite shape and definite volume.

Detailed explanation-4: -Solids are made up of particles (atoms) that do not move about because they are closely packed (touching each other) and held together by strong intermolecular forces. Therefore, they are always in a fixed position and can only vibrate in a fixed position, sending sound waves along its path very fast.

Detailed explanation-5: -In solid atoms are very tightly packed because atoms are very close to each other. Liquids have the arrangement of the atoms looser than that of in solid. In gases, atoms are very loosely packed because of the high kinetic energy of atoms in the gas phase.
