Energy Resources and Storage Questions

Multiple choice zoology meaning of life energy flow and loss energy flow in a food chain energy flows

The best source of energy in the environment is

  1. Water

  2. Soil

  3. Trees

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

Trees are autotrophs or producers in an ecosystem and trap solar energy. The solar energy is converted into chemical energy, which is stored in seeds, fruits and other storage organs. Thus, producers like trees are the source of chemical energy for all the heterotrophic organisms. All the heterotrophs either directly or indirectly depend on the food, synthesized by producers like trees. These organisms directly cannot use solar energy.

Which of the following is the most important conventional natural source of energy?

  1. Atomic energy

  2. Biogas

  3. Sunlight

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

Conventional source of energy is a type of source which is limited in nature like coal, gas, fuel, minerals etc. they take millions of years to replenish. 

So, the correct answer is 'Fossil fuels'

Multiple choice commercial applications bioenergy biofuels making biofuels technological and industrial development

Fossil fuels are 

  1. Conventional resources

  2. Non-conventional resources

  3. Non-renewable resources

  4. Both A and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • Conventional sources of energy are generally non-renewable sources of energy as the accumulation or creation of conventional sources of energy takes years, once they are exploited or consumed. 
  • Fossil fuels are an example of conventional resources. Petrol, diesel, coal, natural gas, etc are examples of fossil fuels that are obtained by the microbial action on the dead matter for a long time. 
  • They are used as a source of fuel and energy from ancient times and it takes years to form once they are exploited.

Thus, the correct answer is option D.

Multiple choice commercial applications bioenergy biofuels making biofuels technological and industrial development

Oil, coal and naturalgas constitute

  1. Renewable source

  2. Fossil fuel

  3. Eontic fuel

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Fossil fuels are the hydrocarbon compounds formed due to the microbial activity on the dead plants and animals. There are different materials which can be referred as the fossil fuels. The coal, natural gas, oil, petrol, diesel are all the components which are obtained from the Earth. These are used as fossil fuels for the production of energy.

Thus, the correct answer is option B. 

Multiple choice commercial applications bioenergy biofuels making biofuels technological and industrial development

The energy obtained from biological resources is called as

  1. Electrical energy

  2. Mechanical energy

  3. Bioenergy

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

Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.

Multiple choice commercial applications bioenergy biofuels making biofuels technological and industrial development

The main source of biomass energy is 

  1. Coal

  2. Heat energy

  3. Thermal energy

  4. Cow-dung
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Organic matter that is obtained from living or dead organisms is called as biomass. Biomass energy is a renewable energy source. Coal, heat energy, and thermal energy are all fossil fuels while biomass is a source of energy available from organic matter like plant and animal wastes.

Thus, the correct answer is option D.

Multiple choice evs atmosphere- wind weather, climate and adaptation of animals to different climates climate and weather weather, climate and adaptations of animals to climate

Which one of the following is a rich source of energy and never causes atmospheric pollution?

  1. Solar energy

  2. Nuclear energy

  3. Sewage

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

 solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies. The solar energy is a promising rich source of energy which does not cause any atmospheric pollution.

so the correct answer is 'Solar Energy'.

Multiple choice commercial applications issues of the environment eco-system and its destruction ecology and ecosystem ecology and ecosysytem

In man subsidized powered ecosystem, power or energy input by man is, in form of

  1. Fertilizers and machines

  2. Tides and waves

  3. waves and currents

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

A man-subsidized ecosystem is one where human intervention provides additional energy to supplement natural processes. Fertilizers and machines are classic examples of such human-provided energy inputs.

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

As the water stored in the reservoir of a dam flows out, its potential energy changes to :

  1. magnetic energy

  2. light energy

  3. kinetic energy

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


The potential energy stored in a reservoir at a given height is converted to kinetic energy (movement energy) which is used to turn a turbine and produce electricity.
Hence, as the water stored in the dam flows out, its potential energy changes to kinetic energy.

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.

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

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.
