Depletion of petrol can be controlled by:

  1. using CNG

  2. using LPG

  3. using kerosene

  4. none of above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Petrol is a limited resource and can be exhausted if not used wisely. Natural gas is stored under high pressure as CNG. CNG can be used as a fuel instead of petrol as it is less polluting. It is a cleaner fuel.

D Correct answer
Explanation

In India, the Petroleum Conservation Research Association(PCRA) advises people how to save petrol/diesel while driving. Their tips include driving at a constant and moderate speed as far as possible, switching off the engine at traffic lights or at a place where you have to wait, ensuring correct tyre pressure, ensuring regular maintenance of the vehicle, etc.

Which of them is used as solvents for dry cleaning?

  1. diesel

  2. Kerosene

  3. Petrol

  4. Paraffin wax
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Dry cleaning is the procedure of cleaning clothes by using chemical solvents (the substance which can dissolve in other substance ). Petrol is a chemical which is used as a solvent for dry cleaning of clothes.


Hence, the correct option is $\text{C}$

On what basis is the windmill designed ?

  1. Average wind velocity

  2. Local environmental

  3. Height and the number of blades of a windmill

  4. All of them
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Average wind velocity and local environmental (geographical) parameters are the basis of deciding the parameters like the height and the number of blades of a windmill. So, during windmill design, all the factors mentioned are taken care of.

Energy can neither be created nor be destroyed, but it can be changed from one form to another. This law is known as:

  1. potential energy

  2. kinetic energy

  3. conservation principle

  4. conservation of energy
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The law of conservation of energy states that the total energy of an isolated system remains constant, it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather, it can only be transformed from one form to another.

For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes. If one adds up all the forms of energy that were released in the explosion, such as the kinetic energy of the pieces, as well as heat and sound, one will get the exact decrease of chemical energy in the combustion of the dynamite.
 Classically, conservation of energy was distinct from conservation of mass; however, special relativity showed that mass could be converted to energy and vice versa by E = mc2, and science now takes the view that mass–energy is conserved.
