The dimensions of Boltzmann constant are the same as that of (i) pressure density (ii) Stefan's constant (iii) Planck's constant (iv) entropy

Explanation

Boltzmann constant
`k = (R )/(N) = (PN)/(TN) = (W)/(TN) = (ML^2T^(-2))/(K)`
` = [M^1 L^2 T^(-2) k^(-1)]`
`Entropy = (Q)/(T) = (ML^2 T^(-2))/(K)`
` [ M^1 L^2 T^(-2) k^(-1)]`
Choice (iv) is correct.
