Test: Conventional Sources of Energy - Question 1

Power plant that uses kinetic and potential energy of water to generate electricity is called

Detailed Solution for Test: Conventional Sources of Energy - Question 1

The power station where electricity is produced by using the energy of flowing water to drive generators is called hydro power plant or hydroelectric power station.

Test: Conventional Sources of Energy - Question 2

Which one of the following is not a fossil fuel ?

Detailed Solution for Test: Conventional Sources of Energy - Question 2

Biogas typically refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source.

Test: Conventional Sources of Energy - Question 3

Choose the incorrect statement regarding wind power

Detailed Solution for Test: Conventional Sources of Energy - Question 3

Because it is maximum in open place ( in open place wind can move fast and freely, so it rotate the blades of windmill at high speed resulting in more energy production.)

Test: Conventional Sources of Energy - Question 4

In a hydroelectric power plant:

Detailed Solution for Test: Conventional Sources of Energy - Question 4

In a hydroelectric power plant potential energy possessed by stored water is converted into electricity.

So option D is correct answer. 

Test: Conventional Sources of Energy - Question 5

Which among the following is not a renewable source of energy ?

Detailed Solution for Test: Conventional Sources of Energy - Question 5

Coal is a non-renewable energy source because it takes millions of years to form.

Test: Conventional Sources of Energy - Question 6

Which of the following is a disadvantage of most of the renewable energy sources?

Detailed Solution for Test: Conventional Sources of Energy - Question 6

Unreliable source is the major disadvantage of the renewable source. For Example: solar energy can be used in the day time when the sun is shining bright. It cannot be used on rainy days or at night time.  

Test: Conventional Sources of Energy - Question 7

Which one is the non-renewable source of energy ?

Detailed Solution for Test: Conventional Sources of Energy - Question 7

Natural gas is a non-renewable fossil fuel formed from the remains of tiny sea plants and animals that died 300-400 million years ago.

Test: Conventional Sources of Energy - Question 8

The use of charcoal is discouraged even though it is a better fuel than coal, because:

Detailed Solution for Test: Conventional Sources of Energy - Question 8

Because charcoal is prepared from destructive distillation of wood, so for this purpose, more and more trees would have to be cut down which causes deforestation. It affects the ecological balance of earth.

Test: Conventional Sources of Energy - Question 9

The main constituent of bio-gas is:

Detailed Solution for Test: Conventional Sources of Energy - Question 9

Gases released in biogas are methane, carbon dioxide, hydrogen and, hydrogen sulfide .but the production of methane is highest (75%). It is the main constituent of biogas.

Test: Conventional Sources of Energy - Question 10

The minimum speed of wind which is required to run a windmill is:

Detailed Solution for Test: Conventional Sources of Energy - Question 10

The minimum wind velocity for a windmill to function is 15 km per hour.
As soon as the speed of the wind becomes less than 15 kilometre per hour, the generator stops working.

Test: Conventional Sources of Energy - Question 11

The capacity of wind mill farm situated in kanyakumari is

Detailed Solution for Test: Conventional Sources of Energy - Question 11

The Muppandal Wind Farm is India's largest operational onshore wind farm. This project located in Kanyakumari district, Tamil Nadu. The project was developed by Tamil Nadu Energy Development Agency. Its installed capacity is 1,500 MW, which makes it one of world's largest operational onshore wind farms.

Test: Conventional Sources of Energy - Question 12

Choose the incorrect statement

Detailed Solution for Test: Conventional Sources of Energy - Question 12

For the correction, option B has to be: The main ingredient of biogas is methane. It burns without smoke and leaves no residue.

Test: Conventional Sources of Energy - Question 13

Major pollutants produced during combustion of fossil fuels are

Detailed Solution for Test: Conventional Sources of Energy - Question 13

Major pollutants produced during combustion of fossil fuels are carbon dioxide, nitrogen oxides and sulfur dioxide into the atmosphere, resulting in potentially devastating long-term contamination of land, air and water resources.

Test: Conventional Sources of Energy - Question 14

In a hydroelectric power plant more electrical power can be generated if water falls from a greater height because:

Detailed Solution for Test: Conventional Sources of Energy - Question 14

In a hydroelectric power plant more electrical power can be generated if water falls from a greater height because greater height means larger potential energy, and this larger amount of potential energy is converted into larger kinetic energy.

Test: Conventional Sources of Energy - Question 15

The power generated in a windmill:

Detailed Solution for Test: Conventional Sources of Energy - Question 15

Power generated in a windmill depends on the velocity with which wind is moving.

Test: Conventional Sources of Energy - Question 16

 Fuel used in thermal power plants is : 

Detailed Solution for Test: Conventional Sources of Energy - Question 16

 Large amount of fossil fuels are burnt every day in power stations to heat up water to produce steam which further runs the turbine to generate electricity.

Test: Conventional Sources of Energy - Question 17

The main constituent of biogas is : 

Detailed Solution for Test: Conventional Sources of Energy - Question 17

Bio-gas is an excellent fuel as it contains up to 75% methane. It burns without smoke, leaves no residue like ash in wood, charcoal and coal burning. Its heating capacity is high. Bio-gas is also used for lighting.

Test: Conventional Sources of Energy - Question 18

 In hydroelectricity power:

Detailed Solution for Test: Conventional Sources of Energy - Question 18

Hydroelectricity power stations use the kinetic energy in moving water. But the water comes from behind a dam built across a river valley. The water high up behind the dam contains potential energy.

Test: Conventional Sources of Energy - Question 19

How many forms of fossil fuels are there

Detailed Solution for Test: Conventional Sources of Energy - Question 19

There are three major forms of fossil fuels they are coal, oil and natural gas. They formed from organic remains of plants and animals that were converted into coal, oil and natural gas by exposure to heat and the pressure of the earth’s crust over millions of years.

Test: Conventional Sources of Energy - Question 20

Trapped heat inside the earth is known as

Detailed Solution for Test: Conventional Sources of Energy - Question 20

Explanation: Geothermal energy is the heat from the earth. It’s clean and sustainable. Resources of geothermal energy range from the ground to water and hot rock. The term geothermal originates from the Greek words.
