Along with Jatropha, the seed oil of which among the following plants has been found to be useful in diesel generators being explored in hundreds of projects throughout India and other developing countries as feedstock for biodiesel?

  1. Arachis hypogea

  2. Pongamia pinnata

  3. Butea monosperma

  4. Pterocarpus santalinius

B Correct answer
Explanation

Pongamia pinnata (also known as Millettia pinnata) is a well-known legume tree whose seeds are rich in oil, making it a primary candidate for biodiesel production alongside Jatropha.

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.

Gasohol is a _____________.

  1. Renewable fuel

  2. Non-renewable fuel

  3. Newly discovered fossil fuel

  4. Combination of renewable and non-renewable resources
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Gasohol is a  combination of renewable and non-renewable resources.
Gasohol is an alternative fuel consisting of a mixture of typically 90 percent gasoline with 10 percent anhydrous ethanol. Gasohol can be used in most modern and light duty vehicles with an internal combustion.
Gasohol is a mixture of gasoline and alcohol (mostly ethanol).

Who is credited with identified petrocrops?

  1. M. S. Swaminathan

  2. M. Calvin

  3. H. Krebs

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

Euphorbiaceae serve as the petroplants. Dr. M. Calvin (1979) was the first to collect the hydrocarbons from plants of Euphorbiaceae. He suggested that these can be the renewable substitute for the conventional petroleum sources. Latex of Euphorbia lathyrus contains fairly high percentage of terpenoids. These can be converted into high grade transportation fuel. 

Thus, the correct answer is option B.

D Correct answer
Explanation

A) Opuntia Ficus-indica can produce oils in vegetative tissues for biofuel production.

B) Ziziphus mauritiana's seed oil meets all the major biodiesel requirements.

C) Pongamia pinata's seed oil can also be used as a biodiesel.

D) Jatropha curcas fruit is capable of producing biodiesel.

So, the correct answer is 'Jatropha'.

One of the following is not a possible reason for use of CNG in automobiles

  1. It can be adulterated

  2. It is cheaper than petrol

  3. It burns more efficiency

  4. It reduces pollution
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Compressed natural gas vehicles require a greater amount of space for fuel storage than conventional gasoline-powered vehicles. Since it is a compressed gas, rather than a liquid like gasoline, CNG takes up more space for each GGE (gasoline gallon equivalent). However, the tanks used to store the CNG take up space in the trunk of a car or bed of a pickup truck which has been modified to additionally run on CNG. This problem is solved in factory-built CNG vehicles that install the tanks under the body of the vehicle, leaving the trunk free (e.g.,  Volkswagen) which sold in countries such as Peru). Another option is installed on the roof (typical on buses), but this could require structural modifications.

SO the correct answer is 'It can be adulterated'.
