Question

Matter is composed of:
A. Atoms
B. Molecules
C. Tiny particles
D. All the above

Answer 1

Hint: Matter is referred to as any substance which is seen by our eyes or felt by our senses. Matter is everything having definite shape or size and occupies volume.

Complete step by step answer:
 Everything in this universe is made up of material which is called matter. A matter is referred to as a substance which has a certain mass and takes up a certain volume in space. For example we human beings are matter as well as a pencil or a vehicle is also a matter.
So matter is both a living and a non-living thing. Matter is composed of atomic and subatomic things (electron, proton and neutron). Matter does not include mass less objects like light, photons and sound.
Matter exists in different phases. The most common are solid, liquid and gaseous phases. We come across different phases of matter every day. Solid ice, water and steam are few examples of matter touched in everyday life.
Subatomic particles are also considered as matter. But they belong to quantum states of matter. Their sizes and positions are not defined at particular times.
Thus option D is the correct answer, i.e. matter is composed of all the above.
As matter is composed of living and non-living objects so option A is incorrect. Water is a part of matter, so it is not the correct option.

Note:
Matter is a broad term. Nearly all things we meet daily are composed of matter. Based on the discovery of electrons, protons and neutrons, hydrogen and helium are found to exist which are primary gases.
