Coefficient of Thermal Expansion of Potassium (K) & Facts, Color, Uses ... 2022

Size of things changes depending on the coefficient of thermal expansion. It's even the case for Potassium. Ok, so what is the coefficient of thermal expansion for an atom of K?

Note: Learn more about the coefficient of thermal expansion here.

In the case of Potassium this thermal coefficient is 82 10^-6 K^-1. By the way, did you know there are cool facts about Potassium that most don't know? Check this...
