19. To separate rocks into different sized particles for road building and other construction
projects, which technique is applicable?
A. condensation
C. sieving
B. evaporation
D. using magnet
20. Which of these is NOT a technique in separating a mixture?

16. Filtration can be defined as the mechanical or physical process used for the separation of one substance from another, such as solids, liquids, and gases, with the aid of an interposing medium like filter.

17. Evaporation is a technique used to separate out homogeneous mixtures. The process typically involves heating the mixture until no more liquid remains.

18. Decantation can be used to separate two liquids that have different densities as long as they are immiscible. For example, water and oil form two separate layers when mixed together. Water being denser settles at the bottom and oil floats on water, forming two distinct layers.

19. Sieving is a simple technique for separating particles of different sizes. A sieve such as used for sifting flour has very small holes. Coarse particles are separated or broken up by grinding against one another and the screen openings.

20. Dissolving is NOT a separation technique.
