Question

Nikhil's father was suffering from high blood pressure and cardiac problems. Doctor suggested him to take low fat milk. Nikhil churned the milk and separated the butter (fat) from it and then he served that milk to his father. Answer the following questions based on above information:

(a) Name the technique by which Nikhil separated butter from milk.

(b) Write any other application of that technique.

(c) Which values are reflected in Nikhil's behaviour?

Answer 1

Answer:

(a) The technique by which Nikhil separated butter from milk was centrifugation.

(b) The other application of centrifugation is the washing machine.

(c) Nikhil possessed the necessary chemical expertise.

Explanation:

• The technique used by Nikhil was centrifugation. The procedure known as centrifugation uses centrifugal force to separate two liquids from a mixture. During this process, the mixture's denser component moves farther from the axis while its lighter component moves closer to the axis.
• Centrifugal washers are the type of washers used to clean soiled clothes.
• Nikhil possessed the necessary chemical expertise. With use of the centrifugal device, he used this to remove the fat from the milk. He provided his father with appropriate service in this manner.

Answer 2

Answer:

(a) Nikhil used centrifugation to separate the butter from the milk.

(b) The washing machine is another device that uses centrifugation.

(c) Nikhil had the required chemical knowledge.

Explanation:

• Nikhil employed centrifugation as his method. Centrifugation is the process of separating two liquids from a mixture using centrifugal force. The mixture's denser component moves away from the axis throughout this operation, while the mixture's lighter component moves in the opposite direction.
• The sort of washers used to clean dirty garments are centrifugal washers.
• Nikhil had the required knowledge of chemistry. He employed this to separate the milk's fat using the centrifugal apparatus. In this way, he gave his father the proper duty.
