sorry I don't know answer of second one really sorry:(

Answer 2

The Boltzmann constant (kB or k) is the proportionality factor that relates the average relative kinetic energy of particles in a gas with the thermodynamic temperature of the gas. ... The Boltzmann constant is defined to be exactly 1.380649×10−23 J⋅K−1.
