A) 273 cal/K
B) 253 cal/K
C) 263 cal/K
D) 293 cal/K
Correct Answer: D
Solution :
[d] Change in entropy is given by \[dS=\frac{dQ}{T}\text{ or }\Delta S=\frac{\Delta Q}{T}=\frac{m{{L}_{f}}}{273}\] \[\Delta S=\frac{1000\times 80}{273}=293\text{ cal/K}\text{.}\]You need to login to perform this action.
