A) \[\Delta {{S}_{system}}>0\,and\,\Delta {{S}_{surroundings}}>0\]
B) \[\Delta {{S}_{system}}>0\,and\,\Delta {{S}_{surroundings}}<0\]
C) \[\Delta {{S}_{system}}<0\,and\,\Delta {{S}_{surroundings}}>0\]
D) \[\Delta {{S}_{system}}<0\,and\,\Delta {{S}_{surroundings}}<0\]
Correct Answer: B
Solution :
[b] Given conditions are boiling conditions for water due to which \[\Delta {{S}_{total}}=0\] \[\Delta {{S}_{system}}+\Delta {{S}_{surrounding}}=0\] \[\Delta {{S}_{system}}=-\Delta {{S}_{surrounding}}\] for process, \[\Delta {{S}_{system}}>0\Rightarrow \Delta {{S}_{surrounding}}<0\]
