Anu wants to make a cake for Priya for her birthday. Because of bad weather she could not go out and but she has 5 litres of milk with her. How can she get cream from the milk?
Centrifugation
In this case we try to increase the effective output of gravity by some processes as there is a difference in the weight of milk and cream the process of centrifugation takes place here. As cream is less denser than milk when we will spin or agitate it, the creamwill be deposited on the upper part of the milk and hence we can get the cream.
