Water in an ice cube tray is put into the freezer section of a refrigerator. As it freezes, this water — A loses all entropy B increases in entropy C decreases in entropy D has constant entropy

Entropy defines as the degree of randomness occurring in the molecules. Entropy depends on the following:-

Entropy depends on heat energy as heat energy alters the motion and randomness of the particle.

According to the question, the correct option is C that is decreased in entropy.

When the water in an ice cube tray is put into the freezer section of a refrigerator. As it freezes, this water entropy decreased because the temperature gradually decreases which slows down the movement of particles and decreases the randomness.

Hence, the correct option is C.

Explanation:

As we know that the entropy is defined as

So here we know that initially in ice tray we put water at room temperature into this

After placing this into the refrigerator the heat is extracted out of the water due to which the entropy of water will decrease

So correct answer here will be

C decreases in entropy

multiply 2kg by latent heat of vap
