5 Chapters
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.
We wear clothes, we change them, we throw them away and then buy them. Interesting isn't it? There are so many things we do with clothes. But where do these clothes come from?They're made of 'Fibres'. Now we use 'Synthetic Fibre'. So, what are synthetic fibres? What are they made of? Let us read more about it ahead.
We all know how useful metals and nonmetals are. Metals and Nonmetals are an important part of our lives. We can’t survive without nonmetals like oxygen, and also without the existence of metals. Let us study all about materials like metals and nonmetals in detail.
Is it possible to live a normal life without coal, petrol, fuel, etc? No, right? Coal, Natural Gas, and Petrol are something that we use on daily basis. What is the science behind all these substances? Let's find out more about it.
Did you know that the Earth is the only planet where fire can burn? Any combustion reaction requires oxygen, so fire is only possible on our planet. In fact, fire is not really a thing as much as it is an event that occurs due to a chemical reaction. Come let us look at Combustion and the learn about the Flame.
Is the air you breathe really 'purified' or the water you drink 'free of external pollutants'? The answer is a big 'NO'.The air we breathe and the water we drink in today's time are actually polluted. Pollution is everywhere and it's high time we start taking actions.Find out more about its types and effects ahead.
