Hydrogen is a cleaner fuel than $CNG.$ 

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Hydrogen gas is cleaner fuel than $CNG$ as $CNG$ contains hydrocarbons which in turn contains carbon and it is a form of pollutant present in $CNG.$  But hydrogen is waste-free. The fusion of hydrogen does not produce any waste and therefore it is cleaner than $CNG.$

Biofuels are different from fossil fuels in regard to greenhouse gases but are similar to fossil fuels in that biofuels contribute to air pollution

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Fuels extracted from plants and crops are known as biofuels. They not only help a struggling economy by providing jobs but also helps in reducing greenhouse gases up to much extent by emitting less pollution. 

Biofuels are produced from wheat, corn, soybean, and sugarcane which can be produced again and again and thus they are sustainable.
Like fossil fuel, biofuel also causes air pollution.

A liquid fuel used in homes is:

  1. Water

  2. LPG

  3. CNG

  4. Cooking oil
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Cooking oil or Vegetable oil can be used as an alternative fuel in diesel engines and in heating oil burners. When vegetable oil is used directly as a fuel, in either modified or unmodified equipment, it is referred to as straight vegetable oil (SVO) or pure plant oil (PPO). Conventional diesel engines can be modified to help ensure that the viscosity of the vegetable oil is low enough to allow proper atomization of the fuel. This prevents incomplete combustion, which would damage the engine by causing a build-up of carbon. Straight vegetable oil can also be blended with conventional diesel or processed into biodiesel or bioliquids for use under a wider range of conditions.

Hence, the correct option is $D$
