The dimensional formula for Boltzmann's constant is

Options

A. `[ML^(2) T^(-2)theta^(-1)]`
B. `[ML^(2) T^(-2)]`
C. `[ML^(0) T^(-2)theta^(-1)]`
D. `[ML^(-2) T^(-1)theta^(-1)]`

Answer

A

Explanation

`k=R/N=[ML^2T^(-2) theta^(-1)]`
`R rarr` universal gas constant
`PV = nRT = R=(PV)/(nT) =W/("Temp") = [ML^2 T^(-2) theta^(-1)]`
`n rarr` Number of moles.
