What is the unit of the Boltzmann constant?
Newton per meter
Joules per Kelvin
Ampere
Candela
Answer
The Boltzmann constant (symbol k) relates the average kinetic energy of particles in a gas with the temperature of the gas. In SI units, its value is approximately 1.38 × 10⁻²³ joules per kelvin (J/K). This means that for every 1-degree increase in temperature, the average kinetic energy of the particles increases by 1.38 × 10⁻²³ joules.
