Question

1. Answer the following questions in brief.
1. What are fossil fuels?
2. Why is anthracite a better coal than peat?
3. Why is petroleum called liquid gold?
4. How can one tap geothermal energy?
5. Why are gobar gas plants cheap sources of power?​

Answer 1

Answer:

1. Fuel formed by natural processes such as containing organic molecules. It is a non renewable source

2.It has highest carbon content, fewest impurities and highest energy density of all types of coal.

3. Because petroleum is liquid and also having many advantages that makes it unique so it is also known as liqiud glod.

4. Dry steam,flash. In these ways we can get geothermal

5. because it contains from wastage of animals and so do not wasted money on it

Explanation:

Rember these are sort keys you have to elaborate as u wishes

Answer 2

Explanation:

1.

A fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing organic molecules originating in ancient photosynthesis that release energy in combustion.

2.

Peat has a lower calorific value than coal (generating less energy per tonne when it is burned) and yet it produces higher CO2 emissions per unit, so it is the least climate-efficient way to produce electricity or heat in Ireland bar none whereas,

Anthracite has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal.

3.

Petroleum is known as Liquid Gold because of its high value in the market. It also serves directly or indirectly as a source for many organic products which are useful to humans. Like gold, it is expensive and difficult to find.

4.

People can capture geothermal energy through:

Geothermal power plants, which use heat from deep inside the Earth to generate steam to make electricity.

Geothermal heat pumps, which tap into heat close to the Earth's surface to heat water or provide heat for buildings.

5.

Its main component is animal dung (gobar – India) along with some other organic matter like dead remains of plants and animals.So, its easily available.
