Frequently Asked Questions | FAQs
Is heat released during crystallization?
When a material crystallizes, it releases heat. This is because the process of crystallization involves the formation of a highly ordered and structured solid from a less ordered liquid or gas phase, which results in a decrease in the overall entropy of the system. This decrease in entropy is accompanied by the release of heat, which is known as the heat of crystallization. The heat of crystallization is a thermodynamic property that depends on the specific material being crystallized and the conditions under which the crystallization occurs.
