Explanation:
Entropy is concept which the describes the state of randomness or disorderliness of particles of a system. The entropic level depends on two important factors:
1. Temperature
2. Physical state of matter
For system A, in going from solid to liquid by dissolution in water the entropy increases. Solids are the most ordered substances followed by liquids. Gases are the most random.
For system B, moving from gas to a condensed state, there is a huge decrease in randomness of the system. The system tends towards more orderliness as the condensing forces changes a gas to a liquid. For this system, entropy reduces.
