Wedmentay Chapter 1 Matter IN -chemistry pariety of things wib diflerent shopess wise is in ruade un of menter The air we breathe, the food we cal. stonc s. clowall drop of water or a porticle of aamd - every thing is matter. We cas also sece as we look around that all the liungs mentioned above occupy space and have mass. ( 0 - other wordf, they have both mass" and volume*") I M Since early tumes, buman betrings have been trying to underwtand their sumed matter in Barly Indian philosophers classined matter in the form of five basic elements - the panch Tatva" - air, earth, fire, sky and water. Aecording to them everything, living or non living. was made up of these IIve basic elements.) Ancient Greek philosophers had arrived at a similar classification of matter. Modern day scientists have evolved two types of classification of matter based on their physical propertes and chemical nature. In this chapter we shall learn about matter based on its physical properties. Chemical aspects of matter will be taken up in subsequert chapters. 1.1 Physical Nature of Matter 1.1 MATTER IS MADE UP OF PARTICLES or a long time, two schools of thought prevailed garding the nature of matter. One school lieved matter to be continuous like a block wood, whereas, the other thought that matter made up of particles like sand. Let us srm an activity to decide about the nature ' - is it continuous or particulate? rake a beaker. inark the level of water. of a gase rod. Observe arry change in water level. What do you think has happened to the salt? Where does it disappear? In order to answer these questions we need to use the idea that matter is made up of particles. What was there in the spoon. salt or sugar, has now spread throughout water. This is flustrated in Fig. 1.1. Fig. 1. 1: When we dissolve salt in water, the pa of salt get into the spaces between pa of water. [1.1.2 HOW SMALL ARE THESE PAR OF MATTER? Activity Take 2-3 crystals of potas permanganate and dissolve th of water. SI unit of mass is kflogram (kg). init of volume is cubic metre . The common unit of measuring volume is sh that .
