Question

A mixture contains three different substances X, Y and Z. They are of the same size, shape
and yellow in colour. X particles are very heavy, insoluble, non-magnetic. Y particles are very
light, insoluble, non-magnetic. Z particles are iron pieces. Which is the best method to separate
X, Y and Z?
(A) Winnowing, Magnetic separation (B) Distillation, Magnetic separation, Winnowing
(C) Sieving, Magnetic separation, Filtration (D) Handpicking, Sieving

Answer 1

Answer:

A) Winnowing and magnetic separation

Explanation:

First use magnetic separation to separate the Z particles

Now use winnowing. Through this you can find that the heavier particles(X)will fall near you and the lighter particles(Y) will fall a bit away from you.

Now you have the X, Y and Z particles separately
