Boltzmann's Constant

Boltzmann's constant is a fundamental physical constant that links the microscopic world of atoms and particles to the macroscopic properties of matter. It represents the amount of energy associated with the temperature of particles at the molecular level. Essentially, it helps us understand how the random motion and energy of tiny particles contribute to observable properties like temperature and entropy. Its value (approximately 1.38 × 10⁻²³ joules per kelvin) allows scientists to connect temperature—a measure we can intuitively understand—with the energy of individual particles in a system.
