Question

Can somebody tell me the 36th question’s answer

Answer 1

Crystallization is a common technique used to purify solids. Two common methods of crystallization are “gradual cooling” and “diffusion”. Gradual cooling involves dissolving the impure solid in a minimum amount of a hot solvent and allowing the resulting solution to cool slowly to room temperature.

It can be used to purify substances, and can be combined with advanced imaging techniques to understand the nature of the substances crystallized.

Answer 2

Explanation:

Crystallisation is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.
