12 Οκτ 2018 · k: the Boltzmann constant. The Boltzmann constant relates an object’s energy to its temperature. In the revised SI, the Boltzmann constant k equals 1.380649 × 10-23 joules/kelvin. k will help to define the kelvin.
A list of physical constants that you will need to finish some of the computation problems in this book.
