In a solid, like a brick or a lump of metal, the atoms or molecules are bound tightly. They can’t move around, or move nearer to or farther from one another. This suggests that almost all solid substances have a set form that’s troublesome to alter, except by powerfully compression or stretching them, or by breaking them apart. However, some solids are elastic, which means their atoms will move apart slightly and are available back along while not breaking to items.

Solids may be light-weight or heavy, arduous or soft, shiny or boring, sharp or sleek. Some, like gossamer crystals, don’t have any color in any respect. The burden of a solid depends on the categories of atoms within it and also the distance between them. Terribly serious solids have compact, big, serious atoms. The stronger the links, or bonds, between them, the tougher it’s to alter the solid’s form.

Some solids type crystals. These have flat faces, straight edges, and sharp corne.

A crystal’s form is predicated on the method the various atoms and molecules within work against one another, like fitting along different-shaped building blocks. With a lot of blocks, the form step by step grows larger, however keeps an equivalent faces, edges, and corners.

It’s troublesome to alter the form of a thick bundle of rope. Unwind the bundle and one strand bends simply. Fibrous solids use plenty of fragile fibers twisted or plain-woven along to make a way stronger material.
