Question

Write a short note of the following-
(a) Hydropower
(b) Petroleum​

Answer 1

(a) Hydropower

Hydroelectricity is the application of hydropower to generate electricity. It is the primary use of hydropower today. Hydroelectric power plants can include a reservoir (generally created by a dam) to exploit the energy of falling water, or can use the kinetic energy of water as inrun-of-the-river hydroelectricity.

(b) Petroleum

Petroleum is a naturally occurring liquid found beneath the earth's surface that can be refined into fuel. Petroleum is used as fuel to power vehicles, heating units, and machines, as well as it can be converted into plastics and other materials.

❣️❣️ANSWER ❣️❣️

✅Hydropower or water power is power derived from the energy of falling or fast-running water, which may be harnessed for useful purposes. Since ancient times, hydropower from many kinds of watermills has been used as a renewable energy source for irrigation and the operation of various mechanical devices, such as gristmills, sawmills, textile mills, trip hammers, dock cranes, domestic lifts, and ore mills.

Petroleum is a naturally occurring, yellowish-black liquid found in geological formations beneath the Earth's surface. It is commonly refined into various types of fuels. Components of petroleum are separated using a technique called fractional distillation, i.e. separation of a liquid mixture into fractions differing in boiling point by means of distillation, typically using a fractionating column.
