What is Dimensional Formula of Boltzmann Constant?
Dimensional Formula of Boltzmann constant is [M1L2T-2K-1]
Derivation of Dimensional Formula of Boltzmann constant
We derive a dimensional formula of Boltzmann constant. For this we already need to know the dimensions of Avogadro number and gas constant
As, Boltzmann Constant = Gas Constant(R)/Avogadro Number(NA)
Thus, Dimensional formula of k = dimensional formula of (R/NA) . . . (1)
Now we calculate the dimensional formula of each quantity individually
Dimensional formula of R= [M1L2T-2K-1] From(PV=nRT)
Dimensional formula of NA= [M0L0T0] (It is 1/mol)
Putting all the above three-dimensional formulas in Equation (1) we get
Dimensional Formula of k = [M1L2T-2K-1] / [M0L0N0]
⇒ Dimensional Formula of k = [M1L2K-1T-2]
Hence, the dimensional formula of Charge is [ML2T-2K-1]
Dimensional Formula of Boltzmann Constant
Dimensional Formula of the Boltzmann constant is [M1L2T-2K-1]. As we know, a dimensional formula is a way of representing a physical quantity in terms of its dimensions.
Boltzmann constant is a physical constant of great significance in physics, especially when discussing the Kinetic Theory of gases. Now let’s learn about the Boltzmann constant and its dimensional formula.
