Whales live in the sea, but they do not belong to the fish family. They are

sea mammals. A baby whale feeds on its mothers milk.

Whales have big heads but no necks. They breathe through their lungs.

Their air-pipes are not joined to their mouths. This means that a whale can swim

underwater with its mouth open and not drown.

Under the whales skin is a thick layer of fat called blubber. People hunt

whales because blubber can be used as oil and whale meat can be eaten.

Chemical Engineering

Chemical Engineering basically is applied chemistry. It is the branch of

engineering concerned wuth the design, construction, and operation of machines

and plants that perform chemical reactions to solve practical problems or make

useful products.

Chemical Engineering

Like all engineers, chemical engineers use math, physics, and economics

to solve technical problems. The difference between chemical engineers and other

types of engineers is that they apply a knowledge of chemistry in addition to other

engineering disciplines. Chemical engineers sometimes are called universal

engineers because their scientific and technical mastery is so road.

Some chemical engineers make design and invent new processes. Some

contruct instruments andfacilities. Some plan and operate facilities. Chemical

engineers have helped develop atomic, science, polymers, paper, dyes, drugs,

plastics, fertilizers, foods, petrochmicals.... pretty much everything. They devise

ways to make products from raw materials and way to convert one material into

another useful form. Chemical engineers can make processes more cost effective

or more environmentally friendly or more efficient. As you can se, a chemical

engineer can find a niche in any scientific or engineering field.
