Boltzmann constant
The Boltzmann constant is a fundamental physical constant that connects the microscopic world of atoms and molecules to the macroscopic world we experience. It helps relate temperature to energy, indicating how much energy is associated with the motion of particles. Essentially, it gives us a way to understand thermal energy at a particle level, playing a crucial role in statistical mechanics and thermodynamics. With a value of approximately 1.38 × 10^-23 joules per kelvin, it allows scientists to make sense of phenomena like heat and temperature in a quantitative manner.
