1.	The entropy change can be calculate by using the expression `DeltaS= ( q_("rev"))/( T)`. When water freezes in a glass beaker, choose the correct statement amongst the following `:`A. `DeltaS`( system ) decreases but`DeltaS`( surroundings) remainsthe same.B. `DeltaS ` ( system ) increases but `DeltaS` ( surroundings) decreasesC. `DeltaS` ( system) decreases but `DeltaS` ( surroundings) increases.D. `DeltaS` ( system ) decreases and`DeltaS` ( surroundings) also decreases.
Answer» Correct Answer - c `DeltaS` ( system)decrease because moleculesin solid ice are less random than in liquid water. However, when water freezes to ice, heat is released which is absorbed by the surroundings. Hence, entropy of the surroundings increases.
