Test: Structure of Matter - JAMB MCQ

The fundamental unit of matter is the atom. Atoms are the building blocks of all substances and cannot be further divided without losing their characteristic properties.

Atoms consist of protons, neutrons, and electrons. Protons and neutrons are located in the nucleus, while electrons orbit around the nucleus. Atoms can combine to form molecules, which are composed of two or more atoms bonded together.

Molecules are formed when two or more atoms chemically bond together. They are composed of atoms held together by chemical bonds. Atoms are the individual particles that make up molecules and can exist independently.

The molecular theory can explain Brownian motion, which is the random motion of particles in a fluid due to collisions with molecules. Brownian motion provides evidence for the existence of molecules and atoms.

Brownian motion refers to the random movement of tiny particles or molecules in a fluid. It occ

A droplet of ink spreading in a glass of water is an example of diffusion. Diffusion is the process by which particles move from an area of high concentration to an area of low concentration, resulting in the uniform mixing of substances.

Surface tension is the property of a liquid that allows it to minimize its surface area and form a curved surface. It is caused by the cohesive forces between the molecules of the liquid.

Capillarity refers to the phenomenon of a liquid rising or falling in a narrow tube against the force of gravity. It is responsible for the rise of liquids, such as mercury, in capillary tubes.

Adhesion refers to the attraction between particles of different substances. It is the force that causes substances to stick or cling to each other.

Cohesion is the force that holds molecules of a substance together. It is responsible for the formation of drops, the surface tension of liquids, and the shape of liquid droplets.
