Assertion: Cream can be separated from curd by centrifugation.
Reason: In centrifugation, immiscible liquids separate out in layers depending on their densities.

The correct answer is option 'C' - (A) is true, but (R) is false.

Explanation:
Centrifugation is a process that uses centrifugal force to separate particles or substances of different densities. It is commonly used in laboratories and industries for various purposes, including the separation of immiscible liquids.

Assertion is true: Cream can indeed be separated from curd by centrifugation. When curd is subjected to centrifugation, the heavier components (curd solids) settle at the bottom, while the lighter components (cream) rise to the top.

Reason is false: The reason provided in the statement is incorrect. Centrifugation does not separate immiscible liquids based on their densities. Instead, it separates substances or particles based on their densities. Immiscible liquids may separate out in layers during centrifugation, but the separation is not solely dependent on their densities.

Centrifugation works based on the principle of centrifugal force, which is the outward force experienced by an object rotating in a circular path. This force causes denser substances or particles to move towards the outer edge of the rotating container, while lighter substances or particles move towards the center.

In the case of cream separation from curd, centrifugation is used to separate the solid curd particles from the liquid cream. The centrifugal force causes the curd solids to settle at the bottom of the container, allowing the cream to rise to the top.

In conclusion, cream can be separated from curd using centrifugation, but the reason provided in the statement is incorrect. Centrifugation does not separate immiscible liquids solely based on their densities, but rather separates substances or particles based on their densities.
