Question

Which of the following results in an increase in the entropy?

Answer 1

Answer- In the given question change of Entropy will be seen in option 4

Explanation - When sugar is dissolved in water the basic hydroxyl ions present in them, which are more in size than the water molecules will present and also these hydroxyl ions might act as a Donor as well as acceptor ions.

For different molecules of water Hence there will be a decrease in entropy at first which would counteract with increase in entropy this happens due to thermodynamics law.

Answer 2

Answer: Dissolving sugar in water

Explanation: The process of cooling something will "remove" energy from any given system, which means decreasing the amount of entropy in the system. Freezing water, cooling a solid or condensing vapor are examples of cooling the given system. Also, the process of dissolution requires energy, it can be mixing with an instrument or the same solubility of sugar, and as you add energy to the system, this increases the entropy.
