Question

1. In a Grade 6 Science class a group of pupils would like to separate
salt from water. What method will they use to separate the
mixture? Explain your answer.
2. In the illustration shown below, explain a few sentences the
technique of separating mixtures and give the benefit of separating
it.

Answer 1

Answer:

Essential, inherent, intrinsic refer to that which is in the natural composition of a thing. Essential suggests that which is in the very essence or constitution of a thing: Oxygen and hydrogen are essential in water. Inherent means inborn or fixed from the beginning as a permanent quality or constituent of a thing: properties inherent in iron. Intrinsic implies belonging to the nature of a thing itself, and comprised within it, without regard to external considerations or accidentally added properties: the intrinsic value of diamonds.

Answer 2

Answer:

(1) Distillation

Explanation:  

• (1) Salt can be removed from water by the process of distillation
• Take the salt water in a beaker and boil it until the water evaporates.
• Water changes to vapor form and salt is left behind in the beaker as solid.
• This happens because the boiling point of water is lower when compared to the salt.
• Another method to separate salt from water is by evaporation. But this is a slow process as compared to distillation.
