Question

Assertion: When milk is churned the cream gets separated from it.

Reason:​ Churning of milk is a centrifugation process.

• A. If ‘A’ and ‘R’ are true and ‘R’ is the correct reason for ‘A’.
• B. If ‘A’ and ‘R’ are true and ‘R’ is not the correct reason for ‘A’.
• C. If ‘A’ is correct and ‘R’ is wrong.
• D. If ‘A’ is wrong and ‘R’ is correct.

Answer 1

The correct option is A

If ‘A’ and ‘R’ are true and ‘R’ is the correct reason for ‘A’.

Answer:

The principle of centrifugation is that the denser particles are forced to the bottom and the lighter particles stay at the top when spun rapidly.

The explanation for the Assertion statement:

• When milk is churned, the cream is separated from it due to centrifugal force because this force acts in an outwards direction.
• Due to this outward force, the heavier particles in milk experience more force than the lighter particle.
• The cream part, being heavier, separates from the milk and gets churned out.

The explanation for the Reason statement:

• When milk is churned, the cream is separated from it due to centrifugal force because this force acts in an outwards direction.
• The principle of centrifugation is that the denser particles are forced to the bottom and the lighter particles stay at the top when spun rapidly.
• The cream part, being heavier, separates from the milk.

Conclusion:

So, Here ‘A’ and ‘R’ are true and ‘R’ is the correct reason for ‘A’.

Therefore, option A is the correct answer.
