I got this question in my homework.

This is a very interesting question from Crystallization in section Crystallization of Food Processing Unit Operations

Answer 1

Right choice is (a) Solid crystals will dissolve into the water

Best explanation: The solid crystals dissolve into the water in the hydrated crystals forming a supersaturated solution. Adding small crystal in the supersaturated solution causes the liquid to change to the solid.
