(a) the principle involved in separation of the mixture

(b) the technique of separation

for kerosene & water mixture.

(a) Principle involved: Based on the separation of two immiscible liquids (one heavy, one light) through separating funnel.

(b) Technique of separation: The kerosene & water mixture is added to the separating funnel and the funnel is kept aside for some time.

The heavier immiscible liquid i.e., water settles down in the separating funnel and is then removed from below on opening the tap and collected out separately.

The lighter immiscible liquid i.e., kerosene remains above the heavier liquid.
