Which of the following energy source is most costly?

  1. Thermal Energy

  2. Hydel Energy

  3. Solar Energy

  4. Fossil Energy

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

Harnessing hydel power / energy is very costly procedure due to construction of large dams across the streams, clearance of vegetation for the development of the project, rehabilitation of the people living nearby the water bodies.

Kerosene burns more rapidly than coke because

  1. It has got more oxygen in it than coke

  2. It is a liquid hydrocarbon

  3. It has a low ignition temperature

  4. None of these

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

Ignition temperature is the minimum temperature at which a substance catches fire. Kerosene has a lower ignition temperature than coke, allowing it to ignite and burn more rapidly.

Destructive distillation of coal leads to the formation of

  1. Wood

  2. Kerosene

  3. Amino acid liquor

  4. Charcoal

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

The destructive distillation of coal produces coal gas, coal tar, and ammoniacal liquor (often referred to as amino acid liquor in some contexts). Wood and kerosene are not products of coal distillation.

Which of the following is not an example of spontaneous combustion?

  1. Burning of liquified petroleum gas

  2. Fire caused in coal mines

  3. Dry white phosphorous liberates white fumes on exposure to air

  4. All of these

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

Spontaneous combustion occurs without an external ignition source. LPG requires an external spark or flame to ignite, so it is not an example of spontaneous combustion.
