Question
Good Morning Sir

Sir like cells are basic unit of our body,matter is also a basic unit of a substance means a group of atoms forms matter and group of matter forms substance.

Sir in this world many substances are there and things, gases , forces, energy ect" And among these forces, energy and matter are classified as main among all the things".
Is this statement is true.

Answer
Hi AM,

What you say is mainly true but a little confused.


Substances and things (material things) are made of atoms. Atoms can join together to form molecules. For example water is made of hydrogen and oxygen (H2O). Water can exist as a gas (steam), liquid (water) and solid (ice). More complex combinations of atoms, molecules  form living matter. Any material thing can be analysed as to its atomic content. Analysis for molecules is much more difficult.

The universe is space, time, matter and forces. That is all there is.

Best wishes.
Kevin.
