Gases do not have a fixed shape due to the weak forces of attraction between the gaseous particles. Hence, they can flow and take shape of the container.

“Churning followed by Coagulation” is employed to separate cheese (Paneer) from milk. There are six important steps in making cheese (Paneer) from milk:
Acidification
coagulation
separating curds and whey
Salting
shaping
ripening
