Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
The value of AS is positive for (1) evaporation of water (2) dissolution of sugar in water (3) crystallisation of salt from brine (4) stretching of rubber bandA) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: B
Solution :
Entropy is the measure of randomness. As the randomness increases, entropy increases. The order of entropy is gas > liquid > solid. Thus,\[\Delta S\]is positive, when water is evaporated (ie, liquid converts into gas) and sugar is dissolved in water (ie, solid converts into liquid).
