Boltzmann Constant

       

Boltzmann Constant Formula
\( k_b =  p \; V \;/\;  T_a \; n \)     (Boltzmann Constant) \( p =  k_b \; T_a \; n \;/\; V \) \( V =  k_b \; T_a \; n \;/\; p \) \( T_a =  p \; V \;/\;  k_b \; n \) \( n =  p \; V \;/\; k_b \; T_a \)

\( k_b \) = Boltzmann Constant (See Physics Constant)	\(lbm-ft^2 \;/\; sec^2\)	\(kJ \;/\; molecule-K\)
\( p \) = Pressure	\(lbf \;/\; in^2\)	\( Pa \)
\( V \) = Volume	\(in^3\)	\( mm^3 \)
\( T_a \) = Absolute Temperature	\( F\)	\( K \)

Boltzmann constant, abbreviated as \(k\) or \(k_b\), is a porportionality factor which compares the average relative kinetic energy of particales in a gas with the temperature of the gas.  The Boltzmann constant is a factor in the field of thermodynamics and statistical mechanics.  It appears in the Boltzmann distribution, which describes the statistical behavior of particles in a gas.
