  1. Class 9th Science –  Matter in our surroundings

  2. Class 9th Science –  Matter in our surroundings Matter in our surroundings is the first Chapter of Class 9th science and one of the very interesting chapter. What is Matter? How do we classify Matter? These are the first question that strikes in the mind of a ‘Class 9th science’  student. So if we have to define Matter we will say:- “Matter is anything which occupies space and has mass”. e.g ..

  3. Class 9th Science –  Matter in our surroundings So, anything that we see, feel, touch around us is matter. A major requirement for anything to be categorized as a matter is that it should occupy space and have mass. On the basis of physical and chemical properties, Matter is classified as below

  4. Class 9th Science –  Matter in our surroundings Characteristics of Particle of Matter • Matter Particles are very very small-Gulaal particles are very small even if we drop a pinch of gulaal in a drum, entire water colour changes, hence we can say that the particles of matter are very very small. • Matter Particles have space between them-If we take a glass of water and dissolve a spoon of sugar, then the water level will not change, this shows that there are spaces between water particles in which sugar particles accommodates. • Matter Particles are constantly moving-If we light an incense stick in one room than the fragrance spreads to other rooms as well, hence we can say that matter particles are moving constantly.

  5. Class 9th Science –  Matter in our surroundings • Matter Particles attract each other-If we will try to break sugar cube and iron nail with force. Sugar cube, will break easily; iron nail will not break even after applying force. This shows that the force of attraction is very strong. Note:-Force of attraction is maximum in the solid particles and minimum in the gaseous particles. Animated lectures on Matter of Class 9 is available at Takshila Learning.
