Boltzmann's Constant

Definition: Boltzmann's constant is a fundamental physical constant denoted by the symbol 'k'. It relates the average kinetic energy of particles in a gas to the temperature of the gas.

Senses:

1. (Physics) The constant that appears in the equation of the ideal gas law: PV = nRT, where P represents pressure, V represents volume, n represents the number of moles of a gas, R represents the gas constant, and T represents the temperature in Kelvins.
2. (Statistical Mechanics) A physical constant used to calculate the entropy of a system, defined as the gas constant 'R' divided by Avogadro's number 'N_A'.

Sample Sentences:

• The value of Boltzmann's constant is approximately 1.380649 × 10^-23 joules per Kelvin.
• To calculate the entropy of the system, you need to multiply Boltzmann's constant by the natural logarithm of the number of microstates.
• Boltzmann's constant is useful in understanding the behavior of particles in thermodynamics and statistical mechanics.
