Question

The dimensional formula for entropy is

• A. [ $ML{T}^{-2}{K}^{-1}$ ]
• B. [ $M{L}^2{T}^{-2}$ ]
• C. [ $M{L}^2{T}^{-2}{K}^{-1}$ ]
• D. [ $M{L}^{-2}{T}^{-2}{K}^{-1}$ ]

Answer 1

Answer: (C)

$Entropy=\frac{heat}{temperature}$ $(\text{Δ}Q=T\text{Δ}S)$
[Entropy]= $\frac{Q}{T}=\frac{[M{L}^2{T}^{-2}]}{[K]}=[M{L}^2{T}^{-2}{K}^{-1}]$
