Question

is crystallization a physical change?

Answer 1

Answer:

The process of formation of solid crystals from a homogeneous solution is called crystallization. It is a physical change.

Answer 2

Answer:

Yes it is a physical change.

Explanation:

Here no chemical bonds are broken and no new chemical bonds are formed, two of the possible requirements for a chemical change. The molecule can be returned to whatever state it was originally.

In crystallization the intact molecules are arranged in a definite, repeating pattern, held together by inter-atomic or inter-molecular forces (sometimes referred to as crystal packing forces), not by new chemical bonds. During the process of crystallization, heat of fusion is released, overcoming the loss of entropy (randomness) the occurs when the more ordered structure is formed.
