Synthetic Fibres and Plastics

Chemistry

Materials: Metals and Non-Metals

Coal and Petroleum

Combustion and Flame

Pollution of Air and Water

Class 8 Chemistry help build a strong foundation for students in Chemistry. The chapter of Synthetic Fibres and Plastics explains the artificial synthetic fibres and the plastics. It also explains the characteristics of these and their uses in different materials. Next, Materials: Metals and Non-Metals divides into two segments of Metals and Non-Metals. You will learn about their properties and applications which will help you classify substances into categories of metals and non-metals. Further, there is a chapter Coal and Petroleum which helps students realize how Natural Gas is our asset and we must not exploit it otherwise it will deplete. It also discusses the ill-effects of Fossil fuels on our environment. Combustion and Flame will enumerate the types of fuels we use at our homes, vehicles and factories. Then, it will tell about various sources of power like CNG, Diesel, coal, charcoal, wood and more. This chapter will tell us how the usage of flames become important for us. Next, we will also learn about how different are the burning of various fuels. Thus, it will give detailed information about consuming flame and the consumption of fuel. Thus, it helps students in getting adequate knowledge about their concepts so they can use it in real life and senior classes.
