Particle nature of Matter *** Advertisement. Ancient Indian philosophers said that all the matter, living or non-living was made up of five basic elements (panch tatva): air, earth, fire, sky and water. As electricity is passed in the tube or the bulb, these gases get ionized and this creates the plasma inside them that glows. There is less kinetic energy among the particles in solids. Therefore, they are able to overcome the forces of attraction and convert into vapor without any external forces. To know more about Physical Nature of Matter, visit here. For example, spreading of ink in water. It is the amount of heat energy that is required to change 1 kg of a solid into liquid at atmospheric pressure at its melting point. Everything is made up of matter. Matter in our surroundings class 9 notes- This is the 1st Chapter of Class 9th Science. Matter in Our Surroundings: For example, sweating cools down our body.
