How do we turn petroleum into energy we use?

1 answer:

7 0

You don't "turn" it into energy; petroleum HAS stored energy (chemical energy).However, you can turn it into ANOTHER TYPE OF ENERGY; usually this is done by burning the petroleum, and using it to drive machinery.

Since burning fuels is wasteful (the efficiency is limited, in theory, to the Carnot efficiency of a heat engine), other options are being explored, such as chemical reactions in a fuel cell. But such technology is not yet used on a large scale.

Chemical Change

A chemical change occurs on the molecular level and produces a new substance. However, a physical change rearranges molecules and does not produce a new substance.

10 examples of chemical changes

Burning of paper and log of wood

Digestion of food

Boiling an egg

Chemical battery usage

Electroplating a metal

Baking a cake

Milk going sour

Various metabolic reactions that take place in the cells

Rotting of fruits

Decomposition of waste

Impacts of Chemical changes

Anytime a new substance is made, a chemical change takes place. Usually two or more materials are combined and a new substance is formed. A chemical change can produce amazing explosions, like fireworks.

Thus, all of the above is the correct answer. Learn more about "Chemical Changes" here
