Question

Match the mixtures in column I with their method of separation in column II.

Column 1	Column 2
a) Oil mixed in water	1) Sieving
b) Iron powder mixed with four	2) Hand-picking
c) Salt mixed with water	3) Decantation
d) Lady's figure mixed with beans	4) Magnet
e) Rice flour mixed with kidney beans	5) Evaporation

Answer 1

(A) Oil mixed in water- 3.Decantation

1. Decantation is defined as the separation process in which two immiscible liquids are separated.
2. The separation of a mixture of oil from water is an example of Decantation.

(B) Iron powder mixed with four- 4.Magnet

1. Magnetic separation is which separation of components of mixtures by using magnets to attract magnetic materials or magnetically susceptible particles or bodies are separated from non-magnetic particles.
2. It is one of the most common and important physical separation techniques.

(C) Salt mixed in water- 5. Evaporation

1. Evaporation is generally defined as a process by which a liquid or solid is transformed into vapor.
2. Salt mixed in water is separated by Evaporation in which liquid heats up to become vapor and salt separates out.

(D) Lady's figure mixed with French beans- 2. Handpicking

1. Handpicking is a method of separation used to separate large sized impurities like pieces of dirt, stone and husk from wheat rice or pulses.
2. Hence Lady's figure mixed with French beans is separated from Handpicking.

(E) Rice flour mixed with kidney beans- 1. Sieving

1. Sieving allows the fine flour particles to pass through the holes of the sieve while the bigger impurities remain on the sieve.
2. Sieving is used when components of a mixture have various sizes.
