What is the entropy change in \(\mathrm{JK}^{-1}\) during the melting of \(27.3 \mathrm{~g}\) of ice at \(0^{\circ} \mathrm{C}\) ? (Latent heat of fusion of ice \(=330 \mathrm{Jg}^{-1}\) )
- A 330
- B 12.1
- C 3.3
- D 33
Answer & Solution
Correct Answer
(D) 33
Step-by-step Solution
Detailed explanation
\(\begin{aligned} \Delta S_f & =\frac{\Delta H_f}{T_f} \\ & =\frac{330 \times 27.3}{273} \\ & =33 \mathrm{JK}^{-1}\end{aligned}\)
