Answer:

here is your answer dear

Coal and petroleum should be used judiciously because they are limited which wil soon get exhausted or finished and these also pollute our environment. Coal and petroleum were formed millions of years ago from the degradation of biomass. These are exhaustible non-renewable resources.

Answer:

Coal - Coal is an organic material that is used as a fuel. Coal is very important as a major source of energy. 35 - 40 percent of the total energy used is derived from coal. The amount of carbon in different types of coal varies. Other combustible and useful substances are also obtained from coal. Years ago, due to the low pressure of the land of vegetation, coal was formed over a period of time. Around 300 million years ago, the earth was filled with thick forests, Kachchhlands and water streams. The vegetation clusters died in the water which later went under the layers of soil. Due to high temperature and pressure in the ground, they turned into special coal. Coal mainly consists of carbon and its compounds. Carbon and hydrogen are also additional nitrogen, oxygen and sulfur. In addition, phosphorus and some inorganic materials are also added.

On the basis of the quantity of unburned carbon, coal is divided into the following four types -

1. Ethreside (94–98 percent) 2. Bituminous (78–86 percent) 3. Lignite (28–30 percent) 4. Peat (27 percent) Bitumen, coal when heated to 1000–1400 ° C in the absence of air Gas, ammonia is obtained. This process is called distillation of coal. Coal in India is mainly found in Jharkhand, Madhya Pradesh, Odisha, West Bengal and Andhra Pradesh.

       Petroleum - Petroleum is a highly useful substance which is very much used in daily life. Like coal, petroleum is also a fossil fuel. It was also formed like coal, due to the pressures of flora and fauna under the earth and due to high pressure and temperature over time. Naturally found petroleum is called crude oil, crude oil, rock oil etc. The dark colored liquid is found in it. Which are separated by the Prabhaji distillation method. Petroleum, diesel, kerosene, natural gas, Vaseline, lubricants, etc. are obtained from efficient distillation.

Coal and petroleum resources are limited. We should use them judiciously.
