Crystal Structure and the Laws of Thermodynamics

Δημοσιεύτηκε στις 20 Δεκ 2016

Crystals
bring order out of chaos. Does their formation violate the laws of
thermodynamics? Materials chemist Dr Suze Kundu explores the
relationship between crystals and entropy, with footage from the Ri
Archives channel.

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.
