Find the change in the entropy in the following process \( 100 \mathrm{~g} \) of ice at \( 0^{\circ} \mathrm{C} \) melts when dropped in a bucket of water at \( 50^{\circ} \mathrm{C} \) (Assume temperature of water does not change)
[BHU (Med.) 2000]
\( \mathrm{P} \)
(a) \( -4.5 \mathrm{cal} / \mathrm{K} \)
(b) \( +4.5 \mathrm{cal} / \mathrm{K} \)
(c) \( +5.4 \mathrm{cal} / \mathrm{K} \)
(d) \( -5.4 \mathrm{cal} / \mathrm{K} \)
