Centrifugation:
Centrifugation is done by using a machine called centrifuge.
Centrifugation is a method for separating the suspended particles of a substance from a liquid in which the mixture is rotated or spun at a high speed in a centrifuge.
Evaporation:
Evaporation is used to separate a solid substance that has dissolve in water or any other liquid.
The use of process of evaporation for separating a mixture is based on the fact that liquids vaporise easily whereas solids do not vaporise easily.
Sublimation:
The changing of a solid directly into vapours on heating and air vapour into solid on cooling is called sublimation.
The process of sublimation is used to separate those substances from a mixture with sublime on heating.
SOLUTION:
I) butter from curd- CENTRIFUGATION
ii) Salt from seawater-
EVAPORATION
iii) camphor from Salt-
SUBLIMATION

Answer:
Hey..!!
(i) Butter from curd can be separated by the technique of centrifugation. (ii) Salt from sea water can be separated by the technique of crystallization or by the evaporation. (iii) Camphor is sublimable but salt is not. So, camphor can be separated from salt sublimation technique.
