  • Question 2
    1 / -0
    Which of the following is used as a solvent in dry cleaning?
    Solution
    Petrol is used as a solvent in dry cleaning because it is a highly vapourising organic solvent. It makes it easier to remove stains.
  • Question 3
    1 / -0
    What is the cause of a very high demand of water even though it is an inexhaustible natural resource?
    Solution
    Water is an inexhaustible natural resource but most often its demand surpasses its availability. This is mostly because a large percentage of water present on the Earth's surface is not suitable for drinking. The freshwater that is available is mostly found in the frozen form (ice, snow, glaciers, etc) and it makes up only a small proportion. Additionally, conversion of seawater to freshwater is not economical and is not favoured.
  • Question 4

    Describe how coal is formed from dead vegetation? What is this process called?
    Solution
