Energy Resources and Storage Questions

Multiple choice physics the essence of change different forms of energy energy conversions energy transformations and energy transfers

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

  1. its temperature increases

  2. larger amount of potential energy is converted into kinetic energy

  3. the electricity content of water increases with height

  4. more water molecules dissociate into ions
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Hydroelectric power plant uses the potential energy stored in water to generate electricity.
Therefore, if we increase the height of it's fall, energy stored will also increase and large amount of potential energy will be converted into kinetic energy, which means more electric energy will be generated.

Choose the incorrect statement regarding wind power.

  1. Energy from moving wind is wind energy.

  2. The potential energy content of wind blowing at high altitudes is the source of wind power.

  3. Wind hitting at the blades of a windmill causes them to rotate. The rotation thus achieved can be utilized further.

  4. One possible method of utilising the energy of rotational motion of the blades of a windmill is to run the turbine of an electric generator.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The energy that we harness from a windmill is the wind energy due to moving air.
Here, option B is wrong as the wind energy does not depend on the altitude when we harness energy from the windmill.

Multiple choice physics the essence of change different forms of energy energy conversions energy transformations and energy transfers

A Wind-mill converts mechanical energy to ________ energy

  1. chemical

  2. electrical

  3. solar

  4. potential
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Wind power is generated by the force wind exerts on the blades of a turbine, causing the turbine's shaft to rotate at a speed of 10 to 20 revolutions per minute (rpm). The rotor shaft is connected to a generator that converts mechanical energy into electrical energy.

Multiple choice geography irrigation and power solar power plant generation of electricity production of electricity from solar energy exploration and conservation of minerals secondary sector : industry

How many thermal power stations are using resources that are non-renewable?

  1. 300 power stations

  2. 200 power stations

  3. 400 power stations

  4. 500 power stations
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Thermal electricity is generated by using coal, petroleum and natural gas. The thermal power stations use non-renewable fossil fuels for generating electricity. There are over 310 thermal power plants in India.

Multiple choice biology towards green energy solar power plant generation of electricity production of electricity from solar energy

___________ was developed after World War II.

  1. Wind energy

  2. Solar energy

  3. Nuclear power

  4. Thermal power
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Nuclear power technology for electricity generation was developed and implemented in the post-World War II era, specifically in the 1950s. Wind, solar, and thermal power technologies have much older roots or were not the primary focus of post-war industrial development.

Multiple choice biology towards green energy solar power plant generation of electricity production of electricity from solar energy

A non-ecofriendly source of energy is

  1. Tidal energy

  2. Wind energy

  3. Solar energy

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

Tidal energy, wind energy and solar energy are non-polluting sources of energy. They do not harm the environment. Nuclear energy is obtained by fission reaction carried out in nuclear reactors. Dumping of radioactive wastes generated during energy production using nuclear reaction causes serious environmental hazards making it non-ecofriendly. Thus the correct answer is option D.

Multiple choice biology living in harmony climate factors abiotic components organisms and environment

Pick the odd one out
Natural gas, Sun, Bio-mass, Wind.

  1. Natural gas

  2. Sun

  3. Bio mass

  4. Wind
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Natural gas is a non-renewable source of energy that is made of hydrocarbons, primarily methane. Its usage is subjected to the exhaustion because its formation takes time. Sun, biomass wind are the renewable sources of the energy. Their usage does not result in their exhaustion.

Hence, the correct answer is 'Natural gas'

What are sources of energy an ecosystem rely on?

  1. Wind energy

  2. Sunlight and Chemical energy

  3. Thermal Energy

  4. Wave energy
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ecosystems are primarily driven by solar energy captured through photosynthesis. In some specialized environments, such as deep-sea hydrothermal vents, organisms rely on chemical energy (chemosynthesis) instead of sunlight.

An inexhaustible non-conventional universal source of energy is

  1. Wind energy

  2. Solar energy

  3. Hydrothermal energy

  4. Tidal energy
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Solar energy is inexhaustible non-conventional resource. Its use is yet to pick up because of requirement of back up system to store and generate electricity during night and during cloudy days. There are three methods of harnessing solar energy- direct heating (e.g., solar cookers), thermoelectric conversion or solar thermal power plants, e.g., steam generation and photovoltaic conversion.

Universal nonpolluting source of energy is

  1. Fossil fuel

  2. Sun

  3. Nucleus

  4. Wind and water
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Renewable source of energy include biomass energy and some forms of inexhaustible energy like solar energy, hydropower, wind power, tidal energy, wave energy, geothermal energy etc. 

Solar energy is universal, inexhaustible, non-conventional resource, which is non-polluting. It is considered universal because solar energy is available on all places and it does not leads to any type of pollution. However, it may not be harnessed easily. Green plants trap solar energy and convert it into chemical energy stored in sugars, which are utilised by all other organisms.

  1. Which of the following is an indirect form of solar energy?

  1. Tidal energy

  2. Kinetic energy

  3. Potential energy

  4. Wind energy
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Tidal energy is the indirect form of solar energy. Tides are the rise and fall of sea levels caused by the combine effects of the gravitational force exerted by the Moon and Sun and the rotation of the Earth. About 1% of the total solar radiation that reaches earth is converted into energy of wind. As the sun heats different parts of the earth at different rates, air circulates from cold to warm areas producing winds.
