Question

The melting point of a solid is $200K$ and its latent heat of fusion is $400calmo{l}^{-1}$. The entropy change for the fusion of 1 mole of the solid $\left(incal{K}^{-1}\right)$ at the same temperature would be

• A. a. $800$
• B. b. $2$
• C. c. $0.2$
• D. d. $80$

Answer 1

The correct option is B b. $2$

As we know,
$\Delta S=\frac{q}{T}=400/200=2$
