Coal and Petroleum Explained

JNVST Class 9 Science Coal and Petroleum Chapter 3 Explained

Have you ever wondered how petrol reaches your bike, how LPG helps you cook food, or how coal produces energy? All these questions lead us to an important topic, JNVST Class 9 Science Coal and Petroleum. In this chapter, students learn about coal, petroleum, natural gas, fossil fuels, their uses, and the need to save these valuable resources.

However, learning science becomes easier when concepts are explained in a simple way. That is where Veda Academy can help. With its JNVST Class 9 Science study material, chapter-wise notes, important questions, and online learning support, students can prepare according to the JNV syllabus. Moreover, Veda Academy's JNV Online Classes help learners understand important concepts from home.

So, if you are looking for Navodaya Class 9 online coaching with easy explanations and exam-focused practice, Veda Academy can support your preparation. Start with JNVST Class 9 Science Coal and Petroleum, understand the concepts, practise regularly, and move one step closer to stronger Navodaya Class 9 exam preparation.

What Are Fossil Fuels?

Fossil fuels are fuels that formed from the remains of plants and animals over millions of years. Coal, petroleum, and natural gas are common fossil fuels. First, dead plants and animals were buried under layers of soil. Then, heat and pressure acted on them for a very long time. As a result, they slowly changed into fossil fuels.

Therefore, coal and petroleum cannot be made again in a short time. That is why we must use them carefully.

What Is Coal?

Coal is a hard, black fossil fuel. It mainly contains carbon. It was formed from dead plants that lived millions of years ago. Over time, plants were buried under soil. The heat and pressure changed the plant material into coal. This slow process is called carbonisation.

Coal has many uses. For example, it is used to produce electricity and make some industrial products. It is also used in some factories.

Products of Coal

Coal gives us useful products such as:

Coke: It is almost pure carbon. It is used to make steel and in metal industries.
Coal tar: It is a thick, black liquid. It is used to make dyes, paints, medicines, perfumes, and other products.
Coal gas: It is used as a fuel in some places.

Thus, learning about these products is important for JNVST Class 9 Science questions.

What Is Petroleum?

Petroleum is a dark and thick liquid found deep inside the Earth. It was formed from tiny plants and animals that lived in seas millions of years ago.

After these organisms died, their remains settled on the sea floor. Layers of sand and clay covered them. Over millions of years, heat and pressure changed them into petroleum and natural gas. Petroleum is also called crude oil. It is separated into different useful products in a petroleum refinery.

Products of Petroleum

Petroleum gives us many useful products. These include:

Petrol
Diesel
Kerosene
Petroleum gas
Lubricating oil
Paraffin wax
Bitumen

For this reason, petroleum is often called black gold.
What Is Natural Gas?
Natural gas is another fossil fuel. We find it deep under the Earth, often near petroleum deposits.

Natural gas mainly contains methane. It burns easily and produces less smoke than many other fossil fuels. Therefore, people use natural gas as fuel in homes, vehicles, and industries. Many vehicles use Compressed Natural Gas (CNG) as fuel. CNG can also produce less air pollution than some other fuels.

Why Are Coal and Petroleum Non-Renewable?
Coal and petroleum are non-renewable resources because nature takes millions of years to form them. However, people use these resources much faster than nature can replace them. As a result, their supply on Earth is limited.

So, we should use these resources wisely. We can save fuel by using public transport, saving electricity, choosing energy-efficient devices, and avoiding unnecessary fuel use. Students should also revise this topic as part of their JNVST Class 9 Science study material before the exam.
Conservation of Fossil Fuels
Coal and petroleum are very useful. However, their careless use can create problems. Burning fossil fuels releases gases and smoke into the air. These gases can increase air pollution and contribute to global warming. Therefore, we should use fossil fuels wisely. Here are some simple ways to save them:

Use public transport whenever possible.
Walk or cycle for short distances.
Switch off lights and fans when not needed.
Use electricity carefully.
Share vehicles when possible.
Choose cleaner sources of energy.
