Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Global warming refers to the overall increase in the tropospheric temperature reflected on the earth's surface. Developing substitutes for chloroform will not allow the build of chloroforms in the atmosphere. Minimal use of nitrogen fertilizers will not allow nitrogen oxides to cause secondary pollutants. Increase in vegetation like forests will make sure that carbon dioxide is used and so it will not cause the greenhouse effect. Limited use of fossil fuels will not add carbon dioxide, methane, oxides of sulphur etc and thus environment can be saved from their deleterious effects. On the other hand increase use of ACs, refrigerators, production of plastic forms and aerosol spray can propellants are harmful to the environment in a great deal because they cause ozone hole as well as global warming.

Hence, the correct answer is 'Increasing use of air conditioners, refrigeration units and the production of plastic foams and propellants in aerosol spray cans.'

Which is not the possible solution for energy crisis?

  1. Wars and attacks

  2. Energy Simulation

  3. Perform energy audit

  4. Common stand on climate change
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

An electricity shortage is felt most acutely in heating, cooking, and water supply. Therefore, a sustained energy crisis may become a humanitarian crisis.

If an energy shortage is prolonged a crisis management phase is enforced by authorities. Energy audits may be conducted to monitor usage. Various curfews with the intention of increasing energy conservation may be initiated to reduce consumption.

Wars and attacks do not solve the problem of energy crisis, on the contrary they destroy the potential sources of energy.

  2. Lighting controls

  3. Delay in commissioning of power plants

  4. Easier grid access
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In few countries, there is a significant delay in commissioning of new power plants that can fill the gap between demand and supply of energy. The result is that old plants come under huge stress to meet the daily demand for power. When supply doesnt matches demand, it results in load shedding and breakdown.

If energy is conserved then why there are energy crisis?

  1. Energy can be lost through heat

  2. Different sources of energy can lost their efficiency with time

  3. Energy can neither be created nor destroyed, but it does change its form. And not all forms of energy are usable and it gets dissipated as heat energy and sound energy

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

Energy can neither be created nor destroyed, but it does change its form. And not all forms of energy are usable and it gets dissipated as heat energy and sound energy. The energy that is wasted cannot be recovered. Moreover, the current sources or energy such as fuels are non-renewable in nature and are rapidly consumed. That is why we are facing energy crisis.
