The molar gas constant (also known as the gas constant, universal gas constant, or ideal gas constant) is denoted by the symbol R or R. It is the molar...

The Boltzmann constant (kB or k) is the proportionality factor that relates the average relative thermal energy of particles in a gas with the thermodynamic...

n} is the amount of substance; and R {\displaystyle R} is the ideal gas constant. It can also be derived from the microscopic kinetic theory, as was achieved...

volume of a gas to the amount of substance of gas present. Avogadro's law states that: The volume occupied by an ideal gas at a constant temperature is...

temperature constant. He observed that when the pressure was increased in the gas, by adding more mercury to the column, the trapped gas' volume decreased...

Avogadro constant, NA, by n 0 = p 0 N A R T 0 , {\displaystyle n_{0}={\frac {p_{0}N_{\rm {A}}}{R\,T_{0}}},} where p0 is the pressure, R is the gas constant, and...

additive constant. The ideal quantum Boltzmann gas overcomes this limitation by taking the limit of the quantum Bose gas and quantum Fermi gas in the limit...

where h is the Planck constant and R the molar gas constant. As useful rules of thumb, a first-order reaction with a rate constant of 10−4 s−1 will have...

monatomic gas is 3 2 k B T N A = 3 2 R T {\displaystyle {\frac {3}{2}}k_{\text{B}}TN_{\text{A}}={\frac {3}{2}}RT} , where R is the gas constant. In an adiabatic...

capacity (heat capacity per unit mass) of a gas. The suffixes P and V refer to constant-pressure and constant-volume conditions respectively. The heat capacity...
