Question

one word for physical nature of matter (11 words)

Answer 1

Answer:

Physical nature of matter: Based on the physical nature of matter there are three States of Matter:

   Solid: Molecules are tightly packed. They are often hard and rigid.

   Liquid: Molecules are loosely packed as compared to that of a solid. They take the shape of the container.

   Gas: Molecules of gases are farther apart when compared to liquid molecules.

To understand the physical nature of matter let us take a solid substance like paper and start cutting it again and again. At some point in time, the paper cannot be cut into smaller pieces. This piece of paper is the smallest particle of paper as of now. But if we observe the paper pieces further we notice that the paper is made up of even smaller particles that are known as atoms. Atoms are the smallest units of any matter. Previously it was assumed that atom is indivisible. But now after various researches and studies, we know that atoms can be divided into smaller particles that are known as electrons, Protons and Neutrons. Looking at tables, chairs, paper etc. we would have never thought that there are spaces between the particles.
