Answer
(a) When a hot saturated solution is cooled the excess solid is generally thrown out in the form of particles having a definite geometric shape. These particles are called crystals.
(b) The process by which crystals are separated or deposited from a hot saturated solution of a substance on cooling gently is called crystallization.
(c) A well-formed crystal from the cooled filtrate of saturated solution used as seed for the formation of large sized crystal is called seed crystal.
E.g., A seed crystal of potassium nitrate (KNO3) is used to prepare a large size crystal of potassium nitrate.
