Question

The dimensional formula for entropy is
(a) [MLT⁻² K¹] (b) [ML² T⁻²]
(c) [ML² T⁻² K⁻¹] (d) [ML² T⁻² K]

Answer 1

Answer:

Boltzmann's constant, and therefore entropy, have dimensions of energy divided by temperature, which has a unit of joules per kelvin (J⋅K−1) in the International System of Units (or kg⋅m2⋅s−2⋅K−1 in terms of base units).

SI unit: joules per kelvin (J⋅K−1)

In SI base units: kg⋅m2⋅s−2⋅K−1
