Sources of Energy Test - 12

Conventional sources of energy are the natural energy resources that are present in a limited quantity and are being used for a long time. They are called non-renewable sources as once they are depleted, they cannot be generated at the speed which can sustain its consumption rate. They are formed from decaying matter over hundreds of millions of years.

Some common examples of conventional sources of energy include coal, petroleum, natural gas, and electricity.

Hence, the correct option is (D).

Alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium nucleus. They are generally produced in the process of alpha decay, but may also be produced in other ways.

Hence, the correct option is (C).

Solar heater works with the help of sunlight but on a Cloudy day there is no sunlight on earth as result of which solar heater will not work.

Hence, the correct option is (C).

Substance with low ignition temperature is highly inflammable and will catch fire very quickly. LPG catches fire easily than others mentioned here.

Hence, the correct option is (B).

Initially when the toy is at rest before winding key it is in static position which consists of potential energy and whereas when it starts moving the potential energy is changed to kinetic energy.

Hence, the correct option is (A).

Production of Atomic energy has no involvement of any type of biological activity.

Hence, the correct option is (A).

A uranium-235 atom absorbs a neutron and fissions into two new atoms (fission fragments), releasing three new neutrons and some binding energy.

Hence, the correct option is (A).

The Nuclear Power Corporation of India Limited (NPCIL) is a government-owned corporation of India based in Tarapur (Mumbai) in the state of Maharashtra. It is wholly owned by the Central Government and is responsible for the generation of nuclear power for electricity. NPCIL is administered by the Department of Atomic Energy, Govt. of India (DAE).

Hence, the correct option is (C).

Artificial satellites and space probes mainly depend upon Solar energy. Solar power is energy from the Sun. Spacecraft that orbit Earth, called satellites, are close enough to the Sun that they can often use solar power. These spacecraft have solar panels that convert the Sun's energy into electricity that powers the spacecraft.

Hence, the correct option is (B).

The glass sheet in the solar cooker creates a greenhouse effect. Glass sheet has a property that allows the infrared rays of shorter wavelength from the sun to get in the device but does not allow the infrared rays of longer wavelength to leave the solar heating device.

Hence, the correct option is (B).

The clothes are dried by the process of evaporation. Therefore the part of light which helps in heating is infrared part of the sunlight.

Hence, the correct option is (B).

Black gold is an informal term for oil or petroleum - black because of its appearance when it comes out of the ground, and gold because it made everyone involved in the oil industry rich.

Hence, the correct option is (A).

Denmark is Country of winds because of highly windy geographical area.

Hence, the correct option is (D).

Thermal power plants produce energy from coal and petroleum as they are most abundent fossil fuels which are available on our planet.

Hence, the correct option is (A).

The blue colour of the blue zone of the candle is due to the combustion of Carbon monoxide. The blue zone at the bottom of the wick of a burning candle is due to burning of carbon-monoxide gas produced by the incomplete combustion of carbon particles in wax. Whereas the non- luminous zone is the outermost zone of the flame where complete combustion of wax takes place.

Hence, the correct option is (B).
