  • Everything around us is made up of matter. Matter can be defined as anything that occupies space and has mass. Matter can be classified into two types:
    • Physical classification of matter: Based on the physical nature of matter.
    • Chemical classification of matter: Based on the chemical nature of matter.
  • 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.
  • Atoms can be divided into smaller particles that are known as electrons, Protons and Neutrons.

Nature and Characteristics of Matter

Nature and Characteristics of Matter

Nature of Matter

  • Anything that occupies space and has mass is known as matter. Everything around us is a form of matter. The huge buildings, bridges, electrons revolving around a nucleus, the DNA in our cells, the surrounding air, the land beneath our feet, etc. all matter.
  • A matter is said to be composed of particles which are basically atoms and molecules. Depending upon its physical state, the nature of matter falls into three categories:


  • The substances in which the particles are held close to each other with strong intermolecular forces are known as solids.
  • The particles are strongly held at their positions and have only vibratory motion. Solids have a definite shape and definite volume. E. g. : Wood, iron etc.


  • Those substances in which the intermolecular forces are weak enough to allow the movement of particles are known as liquids. The particles are held closely and have a higher degree of freedom than solids.
  • Liquids have a definite volume but no definite shape; they generally take the shape of the container in which they are placed. E. g. : water, milk, etc.


  • These types of matter have very weak forces between their molecules and hence the molecules are free to move. The distance between molecules is large as compared to solids and liquids. Gases have neither fixed shape nor a definite volume.
  • They tend to completely occupy the container in which they are placed. E. g. , air, oxygen, hydrogen, methane, etc.


What Are the Physical Nature of Matter?


Physical Nature of Matter

  • Matter is made up of particles. Everything around us is made up of tiny pieces or particles. The particles of matter are constantly moving (they are in motion) .
  • The particles which make up matter are atoms and molecules.

What Are the Three-Physical Nature of Matter?


  • The three states of matter are the three distinct physical forms that matter can take in most environments: solid, liquid, and gas.
  • In extreme environments, other states may be present, such as plasma, Bose-Einstein condensates, and neutron stars.

What Determines the Physical State of Matter?


  • The amount of energy in molecules of matter determines the state of matter. Matter can exist in one of several different states, including a gas, liquid, or solid state.
  • A gas is a state of matter in which atoms or molecules have enough energy to move freely.

What Are the Properties of Matter?


The properties of matter include any traits that can be measured, such as an object՚s density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature, and more.
