Answer 2

Answer:

(i)Centrifugation,

(ii) Evaporation,

(iii) Sublimation.

Explanation:

Centrifugation is a technique used for the separation of particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed. The particles are suspended in a liquid medium and placed in a centrifuge tube. The tube is then placed in a rotor and spun at a define speed.

Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor.

Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state.
