The correct option is C decreases
Entropy is related to randomness of the particles of the system. More the randomness, more is the entropy.
We know that, in a solid, particles are in less random motion than liquid. Thus, the entropy of a solid is less than of liquid.
Hence, the entropy decreases when we make ice cubes.
Why this question?Tips: Entropy is the measure of randomnessof the particles of the system.
