Energy Resources and Storage Questions

Multiple choice

How is tidal energy generated?

  1. Due to the difference in water levels in sea and rivers

  2. Due to fast blowing winds

  3. Due to high and low tides

  4. Both (1) and (3)
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The gravitational pull of Moon on spinning Earth causes the rise and fall in the sea level. This is called high tide and low tide and the difference in water levels between high and low tides gives us tidal energy.

Multiple choice

Consider the following facts:

  1. Wind turbines convert wind energy to mechanical energy.
  2. In harnessing wing energy, off shore wind is steadier and stronger than on shore wind.

Which of the above statement is/ are true?

  1. Only 1

  2. Only 2

  3. Both 1 and 2

  4. Neither 1 nor 2
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A wind turbine is a device that converts kinetic energy from the wind, also called wind energy, into mechanical energy; a process known as wind power. Offshore wind is steadier and stronger than on land, and offshore farms have less visual impact, but construction and maintenance costs are considerably higher.

Multiple choice

Which of the following is a renewable source of energy?

  1. Natural gas

  2. Coal

  3. Wood

  4. Minerals

  5. All of these are non renewable source of energy
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Wood is a renewable source of energy. This is because, we can burn recently grown wood, and we can plant more trees. When oil or coal is used up, it's gone and can't be replaced.

Multiple choice

Which type of energy conversion takes place in a hydroelectric power plant?

  1. Chemical energy into electrical energy

  2. Chemical energy into mechanical energy

  3. Mechanical energy into electrical energy

  4. Electrical energy into mechanical energy

  5. Light energy into electrical energy
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Water of the hydroelectric power plant has mechanical energy, which is transformed into the electrical energy.

Multiple choice

Which of the following statements is not true about the solar and wind energy?

  1. Both are the mechanical forms of energy.

  2. Both forms of energy can be classified as energy in action.

  3. Both types of energy sources cause no pollution.

  4. Both are the forms of renewable energy.

  5. Both types of energy can be converted into electrical energy.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

No, solar energy is a form of heat energy while wind energy is a form of mechanical energy.

Multiple choice

Which of the following is not a correct pair?

  1. Sun - Non-conventional source of energy

  2. Uranium - Nuclear energy

  3. Coal - Inexhaustable sorce of energy

  4. Wind - Free form of energy

  5. Heat - Thermal energy
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

It is an exhaustable source of energy. Its resources are limited.

Multiple choice

Which of the following statements is/are false?

a. Fossil fuels are a great source of energy because they originate from living things. b. The strong heating of coal in the presence of air is called destructive distillation of coal. c. The real source of energy of coal is solar energy.

  1. Only a

  2. Only a and b

  3. Only b

  4. Only b and c

  5. Only c
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This is the correct option as this statement is false. The strong heating of coal in the absence of air is called destructive distillation of coal.

Multiple choice

An energy source is good if it _____.

  1. doesn’t pollute the environment

  2. produces energy efficiently

  3. is cheaper and easily available

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

An energy source is good if it (i)         doesn’t pollute environment (ii)        produces energy efficiently (iii)       is cheap and easily available All are requirements of an energy source. Hence, option (4) is correct.

Multiple choice

Renewable energy provides power from any source that can be replenished. In this context, which non-conventional sources have been harnessed from water for production of Renewable Energy in India?

  1. Wave Energy
  2. Ocean Thermal Energy
  3. Tidal Energy

  1. Only 1

  2. Only 2

  3. 1 and 2

  4. 1, 2 and 3
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Power Generation Projects based on Wave Energy are not yet commercially established in India.

Ocean thermal energy conversion (OTEC) uses the difference between the temperatures of ocean water levels to run a heat engine and produce useful work, usually in the form of electricity.
India joined the tidal power wave with the approval of a commercial-scale tidal power plant in the Gulf of Kutch. 
Therefore, option (2) is the correct answer.

Multiple choice

Which of the following is a renewable source of energy?

  1. Petroleum

  2. Kerosene

  3. Coal

  4. Tree
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Trees are renewable because they can be replanted and grown repeatedly. Petroleum, kerosene, and coal are fossil fuels that take millions of years to form and cannot be quickly replenished.

Multiple choice

The most powerful energy source, if utilised properly, is

  1. biomass energy

  2. wind energy

  3. nuclear energy

  4. geothermal energy
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The most powerful energy source, if utilized properly, is nuclear energy as it is the result of bombarding uranium nuclei by neutrons. Hence, option (3) is correct.

Multiple choice
