Select the incorrect statements among the following.
(i) Bitumen is used for metalling the roads.
(ii) Some inexhaustible natural resources like coal, petroleum and natural gas formed from the dead remains of living organisms are known as fossil fuels.
(iii) Many useful substances are obtained from coal (commercial importance), so it is also called as 'Black gold'.
(iv) Natural gas is used as starting material for the manufacture of a number of chemicals and fertilizers.

  1. (i) and (ii)

  2. (ii) and (iii)

  3. (ii),(iii) and (iv)

  4. All are correct
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

1) Bitumen is the one of the component of petroleum which is used for metalling / surfacing the roads.

2) Coal, petroleum and natural gases are exhaustible natural resources. Hence, this option is wrong.
3) Petroleum is called as 'Black gold' because it gives many useful substances.Hence,this is wrong.
4) Coal is used as starting material for the manufacture of a number of chemicals and fertilizers. Hence option 4 is incorrect.

Multiple choice chemistry rocks and minerals coal petroleum non-renewable sources of energy

Coal is a fossil fuel and it cannot be prepared in a laboratory or industry because the formation of coal :
a. is very slow process.
b. needs very low pressure and low temperature.
c. needs very high pressure and high temperature.
d. causes air pollution.
Select the correct alternative.

  1. a, c and d

  2. b and d

  3. c and a

  4. d and c
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Coal is a fossil fuel derived from organic matter. We get coal deep inside the Earth's crust in coal mines. When dead plants got buried into the bottom of the soil. Due to high pressure and temperature plants gets converted into fossil fuels. If it is burn in large quantity it causes pollution.
