Weekly Quiz Competition

Question 1
1 / -0

Fill in the blank space by choosing the correct word.
The non-usable animal or vegetable products are collectively called ............

A
$$potential$$

B
$$renewable$$

C
$$fossil$$

D
$$biomass$$

Solution

Biomass is biological material derived from living, or recently living organisms. In the context of biomass for energy this is often used to mean plant based material, but biomass can equally apply to both animal and vegetable derived material.
Hence, the non-usable animal or vegetable products are collectively called Biomass.
Question 2
1 / -0

Nuclear fusion produces:

A
argon

B
deuterium

C
helium

D
krypton

Solution

Nuclear fusion reaction takes place in the core of the sun in which 2 molecules of hydrogen combine to form helium molecule.

$$\ _{1}H^{2}+\ _{1}H^{2}\rightarrow \ _{2}He^{4}$$

Hence, option C is correct.
Question 3
1 / -0

Fill in the blank space by choosing the correct word.
Coal and petroleum are commonly called .................... fuels.

A
$$renewable$$

B
$$biomass$$

C
$$fossil$$

D
$$tidal$$

Solution

Coal and petroleum are commonly called fossil fuels because they are formed from the prehistoric remains of dead plants and animals buried deep under the earth's crust under special conditions.
Question 4
1 / -0

Wind-energy map gives information about the

A
Causes of wind

B
Amount of rainfall

C
Intensity of earthquake

D
None of these

Solution

The wind energy map gives information about the trend of wind energy of various locations so that we can make wind farms on the sites which receive higher wind energy compared to other places.
Question 5
1 / -0

The major problem in harnessing nuclear energy is how to:

A
split nuclei?

B
sustain the reaction?

C
dispose off spent fuel safely?

D
convert nuclear energy into electrical energy?

Solution

Major problem in harnessing nuclear energy is ,how to dispose its residue which is highly radioactive in nature. It requires proper waste disposal mechanism.
Question 6
1 / -0

Fill in the blank space by choosing the correct word.
Water stored in the reservoirs of hydro-electric dams has ................. energy.

A
$$tidal$$

B
$$fossil$$

C
$$potential$$

D
$$biomass$$

Solution

$$Gravitational $$ $$Potential$$ $$ energy $$=$$mgh$$ so it depends on height.
So anything at some height have potential energy.

Potential energy is stored energy or the energy of position. The potential energy stored in a body of water held at a given height is converted to kinetic energy (movement energy) which is used to turn a turbine and create electricity.
Hence, water stored in the reservoirs of hydro-electric dams has potential energy.
Question 7
1 / -0

Fuel used in a thermal power plant is:

A
Water

B
Uranium

C
Biomass

D
Fossil fuel

Solution

A Thermal power plant is a power plant where steam produced by the burning of fossil fuels is used to drive a steam turbine. This turbine is connected to an electrical generator.
Question 8
1 / -0

Sun is the ultimate source of energy for the earth.

A
True

B
False

C
Ambiguous

D
Data insufficient

Solution

The sun is the ultimate source of almost all kinds of energy on earth, either directly or indirectly.

Directly sun gives us solar power and is perfect non-conventional energy source. Moreover, Fossil fuels (coal, oil and gas) are the transformed forms of plants (and animals) which once lived on the earth and grew capturing the energy of the sun. Biomass is a product of photosynthesis where the sun has the major role. Hydro-electricity depends upon the water cycle which again is dependent on solar radiation. Similarly, wind energy, tidal power, wave power all, in some way or other, and depend on the sun.
Question 9
1 / -0

The main constituent of biogas is:

A
Methane

B
Carbon dioxide

C
Hydrogen

D
Hydrogen sulphide

Solution

Biogas typically refers to a mixture of gases produced by the breakdown of organic matter in the absence of oxygen.
Hence, its main constituent will be methane.
Question 10
1 / -0

The source of energy of the hot water spring is geothermal energy.

A
True

B
False

C
Ambiguous

D
Data insufficient

Solution

Geothermal energy is the heat from the Earth. It's clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.
