Question

What does a solid have?

Answer 1

Hint:We know that there are three states of matter, i.e., solid, liquid, and gas. All of them are distinguished by some properties like volume, intermolecular forces, shape, compressibility, thermal expansion, the energy of the molecules, etc. The space between the molecules in the solid is very less.

Complete step-by-step answer:Usually, we know that there are three states of matter, i.e., solid, liquid, and gas. . All of them are distinguished by some properties like volume, intermolecular forces, shape, compressibility, thermal expansion, the energy of the molecules, etc.
We can define all the properties in the solid by the arrangement of the molecules in it. In solids, the molecules are arranged in a very close manner, they have very little space between them due to which the movement of the molecules is restricted. Due to this restriction in the movement, there is no translatory or rotator motion only vibrations can occur in solids.
Now since the solids have a close arrangement of molecules, they have high density and possess a definite shape that is separated by a boundary. They also have a definite volume. Due to less space, the energy of the molecules is also nil and they have the least compressibility.
Thermal expansion in solids is also the least because there is the least energy in the molecules.
As the molecules are very close to each other, the intermolecular forces are very strong in solids.
Therefore, we can say that the solids have a definite shape and volume.

Note:In liquids, there is a considerable space between the molecules due to which the density decreases and the shape are also not proper and in gases, the space between the molecules is very high due to which the density is the least and there is no shape.
