    Large amounts of solar energy are stored in the oceans and seas. The process of harnessing this energy is called

    • A.

      OTEC (ocean thermal energy conversion)

    • B.

      OTC (ocean thermal conversion)

    • C.

      OSTEC (ocean and sea thermal energy conversion)

    • D.

      OTEC(Ocean technology of energy conversion)

    Correct Answer
    A. OTEC (ocean thermal energy conversion)
    Explanation
    The correct answer is OTEC (ocean thermal energy conversion) because it accurately describes the process of harnessing solar energy stored in the oceans and seas. The other options, OTC, OSTEC, and OTEC (Ocean technology of energy conversion), do not accurately represent the process or the specific term used to describe it.

    A much cheaper and lighter fuel extracted from crude oil is used to adulterate petrol in the ratio of 3:1 (adulterant: petrol). It causes damage to the vehicle engine, besides leading to high emission levels. Name this common adulterant of petrol that most easily escapes detection.

    • A.

      Diesel

    • B.

      Kerosene

    • C.

      Naphtha

    • D.

      Mobile oil

    Correct Answer
    C. Naphtha
    Explanation
    Naphtha is a much cheaper and lighter fuel extracted from crude oil that is commonly used to adulterate petrol. It is mixed in the ratio of 3:1 (adulterant: petrol). The use of naphtha as an adulterant in petrol can cause damage to the vehicle engine and also leads to high emission levels. Naphtha is difficult to detect as an adulterant, making it the most easily escaping adulterant of petrol.

     Some people disapprove of wind turbines because:

    • A.

      They do not like windmills.

    • B.

      They get in the way of photographs.

    • C.

      Wind farms are not real farms.

    • D.

      They are often built in areas of natural beauty.

    Correct Answer
    D. They are often built in areas of natural beauty.
    Explanation
    Wind turbines are often built in areas of natural beauty. This suggests that some people object to wind turbines because they believe that the construction of these turbines in scenic locations can negatively impact the aesthetic appeal of the area.

    Natural gas is transported mainly by

    • A.

      Pipelines

    • B.

      Trucks

    • C.

      Auto rickshaw

    • D.

      All three equally

    Correct Answer
    A. Pipelines
    Explanation
    Natural gas is primarily transported through pipelines due to their efficiency, reliability, and cost-effectiveness. Pipelines provide a safe and secure means of transporting large volumes of natural gas over long distances. They are designed to minimize leakage and ensure the smooth flow of gas without any interruptions. In contrast, trucks and auto rickshaws have limited capacity and are not suitable for transporting large quantities of natural gas. 

    Rate this question:

  • 9. 

    How much of the energy in burning coal reaches the consumer as electricity?

    • A.

      1/3 (one-third)

    • B.

      1/2 (one-half)

    • C.

      3/4 (three-quarters)

    • D.

      9/10 (nine-tenths)

    Correct Answer
    A. 1/3 (one-third)
    Explanation
    The answer is 1/3 (one-third).  A significant amount of energy is lost as heat during the conversion process. This loss occurs in various stages, such as the generation of steam, the turning of turbines, and the transmission of electricity. As a result, only one-third of the energy in burning coal actually reaches the consumer as electricity.

    Plastic was once hailed as a "wonder material" but is now becoming a serious environmental and health problem due to its non-biodegradable nature. The burning of plastics, especially PVC, releases the following harmful gases into the atmosphere.

    • A.

      Dioxins

    • B.

      Le

    • C.

      O

    • D.

      Pl

    Correct Answer
    A. Dioxins
    Explanation
    Plastic, especially PVCs, when burned releases dioxins into the atmosphere. Dioxins are highly toxic and persistent chemicals that can have detrimental effects on the environment and human health. They can accumulate in the food chain, causing long-term damage to ecosystems and posing risks to human populations. Therefore, the burning of plastics, including PVC, contributes to the serious environmental and health problems associated with non-biodegradable materials.

    .………………..of power consumed by incandescent bulbs gets wasted in the form of heat.

    • A.

      60%

    • B.

      75%

    • C.

      85%

    • D.

      50%

    Correct Answer
    C. 85%
    Explanation
    Approximately 85% of the power consumed by incandescent bulbs gets wasted in the form of heat. Incandescent bulbs work by passing an electric current through a filament, which then emits light. However, this process is not very efficient, as a significant amount of energy is lost as heat instead of being converted into light. Therefore, only a small percentage of the power consumed by incandescent bulbs is actually used to produce light, making them highly inefficient compared to other types of lighting technologies.

    Which one is not in National Action Plan on Climate Change?

    • A.

      National Mission for Sustainable Agriculture

    • B.

      National Mission on Sustainable Habitat

    • C.

      National Mission for Enhanced Energy Efficiency

    • D.

      National Mission for Energy Conservation

    Correct Answer
    D. National Mission for Energy Conservation
    Explanation
    The National Mission for Energy Conservation is not a part of the National Action Plan on Climate Change. Although energy conservation is an important aspect of addressing climate change, it is not specifically mentioned as a separate mission within the plan. The other options, National Mission for Sustainable Agriculture, National Mission on Sustainable Habitat, and National Mission for Enhanced Energy Efficiency, are all included in the National Action Plan on Climate Change as specific missions to address different aspects of climate change mitigation and adaptation.
