Question

When the liquid is spun rapidly, the denser particles are forced to the bottom and the lighter particles stay at the top. This principle is used in: (a) Centrifugation (b) Fractional distillation (c) Evaporation (d) Tunneling

Answer 1

Answer:

a) centrifugation is the right option

Explanation:

Answer 2

When the liquid is spun rapidly, the denser particles are forced to the bottom and the lighter particles stay at the top. This principle is used in centrifugation. (Option a)

• Centrifugation is a technique used to separate heterogeneous mixture i,e;  solids from liquids.
• If the size of the solid particle is extremely small, during filtration they will easily get transferred through the filter paper.
• Therefore, the centrifugation technique is used in situations where filtration and other such separation methods are not applicable.
• This technique uses centrifugal force to separate particles based on their difference in densities.
• The denser particles get deposited at the bottom during the fast spinning, due to the action of gravitational force.
