Q: What is boltzmann constant?

Flexi Says:

According to kinetic molecular theory, the average kinetic energy of gas particles is dependent upon the temperature of the gas. The average kinetic energy of a gas can be calculated with the following equation:
KE=12mv2=32kT , where v is the mean translational velocity of the molecules, m is their mass, k the Boltzmann constant, is equal to 1.380649 × 10⁻²³ joule per kelvin (K), and the temperature T is expressed in Kelvin. The equation states that the average translational kinetic energy, KE of the molecules is directly proportional to the temperature T of the gas.
