Question

Q1) What is an alloy?
Q2) What is petroleum?
Plz define the following (in photo)

Answer 1

1.

Alloy :-

Alloys are mixtures of two or more elements, one being a metal, usually combined at very high temperatures. By alloying elements, you can create a product that is much stronger, harder, durable, etc., than the individual components. Molybdenum steel is extremely strong and durable - more so than just steel - which is an alloy of iron, carbon and other minor additives.

2.

Petroleum :-

Petroleum is essentially various lengths of hydrocarbons often arranged in chains, that is chains of hydrogen and carbon that can be arranged in various other shapes, that is extracted as a liquid. Many say it is dead animal and plant life, but many believe it is the result of abiotic processes because planets in our solar system have hydrocarbon such as methane and never had any animal or plant life.





3.

fractional distillation : -


the process of separating the constituents of a liquid mixtureby heating it and condensingseparately the componentsaccording to their different boiling points.








4.

coal :-


 a hard, black substance that is dugfrom the earth in pieces, and can beburned to produce heat or power




5. Natural gas :-

Natural gas is gas which is found underground or under the sea. It is collected and stored, and piped into people's homes to be used for cooking and heating.





6.

Energy Crisis :-

An economic problem caused by a dwindling supply of energy, at an increasing price




7.

Exhaustable Resources :-



completely or almost completely depleted of resources or contents

… crops are grown in the resulting field for a year or a few years until the soil isexhausted, and then the field is abandoned …

 —Jared Diamond

Answer 2

coal= a piece of glowing carbon or charged wood.
natural gas= natural gas is a mixture of gases which are rich in hydrocarbon .
fractional distillation = fractional distillation is a process by which components in a chemical mixuture.
