why do molecules in solid are tightly packed
Answers
Answer:
In a solid, particles are packed tightly together so they are unable to move about very much. Particles of a solid have very low kinetic energy. The electrons of each atom are in motion, so the atoms have a small vibration, but they are fixed in their position.
Answer:
Solids can be considered to be hard as a rock or soft as fur. The key to a solid is that it holds its shape and won't flow like a liquid. A rock will always look like a rock unless something happens to it. The same goes for a diamond. A solid can hold it's shape because they have particles (ions, atoms or molecules) that are closely packed together. In a solid, particles are packed tightly together so they are unable to move about very much. Particles of a solid have very low kinetic energy. The electrons of each atom are in motion, so the atoms have a small vibration, but they are fixed in their position. Solids have a definite shape. They do not conform to the shape of the container in which they are placed. Solids can only change their shape by force, as when broken or cut. They also have a definite volume. The particles of a solid are already so tightly packed together that increasing pressure will not compress the solid to a smaller volume. Solids can be transformed into liquids by melting, and liquids can be transformed into solids by freezing. Solids can also change directly into gases through the process of sublimation, and gases can likewise change directly into solids through deposition.
