  • Question 1
    1 / -0
    Natural resources which are limited are called as _________.
    Solution
    Natural resources which are present in a limited amount in nature are called non-renewable sources. They are prepared by natural processes in a long duration of time and have limited supply. Hence, they are non-renewable.
  • Question 2
    1 / -0
    What is used in manufacturing of steel?
    Solution
    Coke is used in the manufacture of steel and extraction of many metals.
  • Question 3
    1 / -0
    Which of the following is a non-renewable source of energy?
    Solution
    Coal, petroleum, and natural gas all are non-renewable sources of energy. These are energy sources that can not be replenished at the rate at which they are consumed. This is because these energy sources require millions of years for formation.
    Option $$D$$ is correct.
  • Question 4
    1 / -0
    When heated in air, coal burns and produces mainly: 
    Solution
    The combustion of coal gives energy and releases carbon dioxide gas.
  • Question 5
    1 / -0
    Choose the correct statement from the following :
  • Question 6
    1 / -0
    Fossil fuels are obtained from :
    Solution
    Fossil fuels are combustible hydrocarbons formed millions of years ago from the dead decaying plants and animals buried under sediment. 

    Over millions of years, these decaying remains were covered by layers and layers of silt and buried deep underground. 

    The pressure and heat at those depths transformed them into the fossil fuels oil, natural gas and coal.

    Hence the correct option is D.
  • Question 7
    1 / -0
    Which of the following is not a natural resource?
    Solution

    Correct option- $$D$$

    Explanation:

    • Natural resources are naturally occurring materials that are useful to man.
    • Minerals, Water, and Soil are natural resources.
    • Plastic is man-made and not a natural resource.

  • Question 8
    1 / -0
    The petroleum product used as fuel for stoves, lamps and jet aircraft is ______.
    Solution
    The petroleum product used as fuel for stoves, lamps, and jet aircraft is kerosene. One of the primary reasons why jets rely on kerosene is due to its low freezing point. Aviation kerosene has a freezing point of -47°C. As a result, planes need to use fuel with a low freezing point, like kerosene so the fuel functions properly without solidifying during the flight.
    Hence the correct option is A.
  • Question 9
    1 / -0
    Naphthalene balls are obtained from coal tar and are used as:
    Solution
    Naphthalene is an aromatic hydrocarbon with a concentrated penetrating odour and is used as moth repellents. Mothballs and other products containing naphthalene are solids that turn into toxic gas. The toxic gas kills insects and may repel animals.
  • Question 10
    1 / -0
    What is formed from a natural process from mostly animal residues and is an example of fossil fuel? 
    Solution
    • Petroleum is formed from natural processes from animal residues under high temperature and pressure conditions. It is a fossil fuel.
    • Biogas is formed from domestic waste, but it is not a fossil fuel. 
    • Hydrogen is used as a fuel but it is not a fossil fuel. 
    • Also, fossils are animal remains, but they are not fossil fuels.  

    So, correct option is C (petroleum)
