NCERT Solutions For Class 8 Science Chapter 5
Here we have provided NCERT Solutions for Class 8 Science Chapter 5 for the ease of students so that they can prepare better for their exams.1. What are the advantages of using CNG and LPG as fuels?
The following are some benefits of using LPG and CNG as fuels: Burning LPG and CNG is easy. When burned, CNG and LPG produce a lot of heat energy. Pipelines make it easy to transport LPG and CNG. When burned, clean fuels like LPG and CNG don't produce smoke.2. Name the petroleum product used for surfacing of roads.
Bitumen is used for the surfacing of roads.3. Describe how coal is formed from dead vegetation. What is this process called?
Millions of years ago, natural processes buried dense forests beneath the dirt. They became further crushed as more and more dirt was put on top of them. They were exposed to extremely high pressure and temperature as a result. These harsh conditions caused them to gradually turn into coal. Carbonization is the term used to describe the entire process by which dead plant turns into coal.4. Fill in the blanks.
(a) Fossil fuels are ____________, ____________, and ____________ .
(b) The process of separation of different constituents from petroleum is called _____________.
(c) The least polluting fuel for a vehicle is ______________.
(a) Fossil fuels Coal, Petroleum , and natural gas . (b) The process of separation of different constituents from petroleum is called refining . (c) The least polluting fuel for a vehicle is Compressed Natural Gas (CNG).5. Tick True/False against the following statements.
(a) Fossil fuels can be made in the laboratory. (T/F)
(b) CNG is a more polluting fuel than petrol. (T/F)
(c) Coke is the most pure form of carbon. (T/F)
(d) Coal tar is a mixture of various substances. (T/F)
(e) Kerosene is not a fossil fuel. (T/F)
a) False b) False c) True d) True e) False6. Explain why fossil fuels are exhaustible natural resources.
Fossil fuels form over millions of years. Fossil fuels cannot be created in a lab; instead, tremendous temperatures and pressure are necessary for the decomposing plants and animals that are buried deep inside the earth. Fossils are thus scarce. As a result, using fossil fuels too quickly will cause them to run out.7. Describe the characteristics and uses of coke.
Characteristics:
i) Coke is tough. ii) Coke is porous. iii) Coke is black.Uses:
i) In the manufacture of steel. ii) In the extraction of metals (as a reducing agent).8. Explain the process of the formation of petroleum.
Sand and clay layers accumulated on top of dead species that had been submerged in the water millions of years ago. These dead organisms turned into petroleum and natural gas as a result of the extreme heat, pressure, and lack of air.9. The complete power shortfall in India between 1993 and 1999 is displayed in the following table. Present the information in a graph. Plot the percentage of scarcity for each year on the X- and Y-axes.
