Thermodynamics: The 2016 advent calendar
Day 20

Crystals and entropy

Suze Kundu explores the relationship between crystals and entropy.

Crystals are highly ordered structures. Their molecules align in regular patterns across three-dimensional space.

Does the formation of crystals violate the second law of thermodynamics? After all, if entropy is always increasing, how can complex stable structures like crystals form? Chemist Suze Kundu explains the nature of crystals and how they can exist without violating the laws of thermodynamics, with the help of some beautiful footage from our recently released Bragg video archive.
