NCERT Solutions for Class 9 Chapter 1 Matter In Our Surroundings


Everything that we see around us is made up of material which is called a matter. The matter is made up of particles and these particulars are very small. The particles of matter have space between them, they are continuously moving and attract each other. The matter around us exists in 3 different states – solids, liquids and gases. The state of matter can be changed by changing temperature or pressure. Matter is one of the fundamental constituents that make up everything in the universe – from minute sand particles on earth to the enigmatic black holes at the centre of many galaxies. Matter has a role to play in everything that we see around us, interacting to form new materials, some familiar and others exotic.
