Question

Identify the characteristics of solids.
(A) Solids have fixed shape and size.
(B) Solids have a strong intermolecular force of attraction between their molecules.
(C) Solids are rigid.
(D) All of these.

Answer 1

Hint : This question requires the knowledge of basic properties of a solid material. Solid is one of the three basic states of matter, the other two being liquid and gas. Because the energy of atoms lowers when they take up a reasonably ordered, three-dimensional structure, a solid can be formed from a liquid or gas.

Complete Step By Step Answer:
Solids have certain features that distinguish them from liquids and gases. They can, for example, withstand any force that is applied to their surface. The solid-state of a compound, on the other hand, is mostly determined by the properties of atoms, such as their organization or the forces that exist between them.
Solids are incompressible, which means that the constituent particles are grouped close together and that there is very little space between them. This makes them very rigid.
Solids are inflexible. This is because there isn't enough space between the constituent particles, causing it to be hard or fixed.
Solids have a compact arrangement of constituent particles due to their fixed mass, volume, and shape.
Molecules have a short intermolecular distance. The force between the constituent particles (atoms, molecules, or ions) is extremely strong as a result of this.

Note :
Solids with a characteristic geometry are known as crystalline solids. There are clear long-range groupings of particles (atoms, molecules, or ions) across the 3-dimensional network of a crystal in such materials. Sodium chloride, quartz, diamond, and other minerals are examples. The other form of solids are amorphous solids that have rigidity and incompressibility to a particular extent.
