Chapter-5 Coal and petroleum Extra Questions

Explanation:

The formation of fossil fuels takes millions of years. They are restricted in nature and can't be recharged effectively, once consumed. As a result, they are regarded as untapped natural resources. 

Explanation:

Cocaine's properties include: Carbon is 98% pure in coke. It is a dark, tough, and porous substance. There is very little smoke produced. 

Cocaine intake: Coke is an extremely useful fuel. It works well as a reducing agent. In metallurgical processes, it is frequently used to remove oxides from metals. It is used to make gas out of water. 

Explanation:

The burial of aquatic plants and animals beneath the sea bed results in the formation of petroleum. The marine plants and animals perished thousands of years ago and settled in the ocean's bottom. This organic matter is broken down by microorganisms under anaerobic conditions. Tiny animal and plant remains were slowly transformed into petroleum by high pressure and heat. 

Explanation:

Natural processes like flooding and earthquakes, among others, buried trees, plants, ferns, and forests beneath the rocks, soil, and sand millions of years ago. They became compressed slowly as more soil fell over them. High temperatures and pressure developed as a result of this. The carbon-rich organic matter of wood was transformed into coal under these conditions and the anaerobic conditions.Carbonisation is the slow process by which wood becomes coal.

Explanation:

Using CNG and LPG as fuel has the following advantages: 

● They do not pollute because they burn with a smokeless flame. 

● When they burn, they produce no ash. 

● They are convenient to store and easy to handle. 

Explanation:

Because of their limited nature, fossil fuels are natural resources that can't be used up. This is because human activity will eventually run out of them. 

Explanation:

The sluggish course of transformation of dead vegetation into coal is called carbonisation.

Explanation:

Coal tar is the result of the vapors that condense in the water during destructive coal distillation. 

Explanation:

Because it comes from the remains of dead organisms, petroleum is referred to as a fossil fuel. 

Explanation:

Petrol is framed by the decay of amphibian plants and creature remains. Petroleum is obtained in India from oil wells in Bombay High and Assam. 

Explanation:

Disastrous refining is the most common way of warming a substance without any air. Coal is destructively distilled into coke.

Explanation:

Refining is the process of separating the various petroleum fractions, and it is carried out in a refinery. 

Explanation:

No, because the conditions necessary for their formation cannot be met in the laboratory, their formation takes a very long time. 

Explanation:

Petrol is combination of different hydrocarbons having different limits. The boiling point rises in tandem with an increase in the number of carbon atoms. Fractional distillation is the term used to describe this property, which is used to separate the various petroleum components. 

Explanation:

The following are the benefits of using energy wisely: 

● The energy crisis will be put off by it. 

● The scientists will have more time to come up with more effective alternative energy sources as a result. 

Explanation:

Fossil fuels are made from the remains of dead organisms that were buried under the earth for millions of years. Petroleum and coal are two fossil fuels.

Explanation:

In India, the Oil Protection Exploration Affiliation (PCRA) encourages individuals how to save petroleum/diesel while driving. 

They advise: 

● Maintain a steady, moderate speed. 

● When the lights come on, turn off the engine. 

● Make sure the tyre pressure is correct. 

● Make sure the car gets serviced on a regular basis. 

Explanation:

Uses: 

● Petrol is utilized as a solvent for dry cleaning, aviation fuel, and motor fuel. ● At home and in jet aircraft, kerosene is used as fuel. 

● Diesel is the fuel of choice for electric generators and heavy vehicles.

Explanation:

During the crude oil refining process or during the extraction of natural gas during processing, liquefied petroleum gas is produced. This process produces mostly propane and butane, with a few other gases in small amounts. These gases are condensed through compression to make them simpler to ship and store. 

To condense the fuel, gases are put away in durable tanks and held at high tensions — multiple times barometrical strain. Due to the extreme pressurization, these tanks have additional safety features, most notably a built-in shutoff valve to seal the tank in the event of leaks and an extra-sturdy design.Because LPG typically does not have an odor, small amounts of ethanethiol—a type of mercaptan with a bad smell—are added to assist people in recognizing potentially hazardous gas leaks. 

Explanation:

The main sources of nitrogen oxide emissions are:

Excess nitrogen in the atmosphere is deposited on land in the form of nitrogen oxides or ammonia, where it is washed into nearby bodies of water. Cars and trucks Coal-fired power plants Large industrial plants Ships and planes Pollution, harmful algal blooms, and oxygen-poor bodies of water are all caused by these excess nutrients. These locations have too much ammonia and low pH, making it difficult for aquatic life to survive.

Both smog and acid rain are caused by the release of nitrogen oxides into the atmosphere when fossil fuels are burned.
