Question

Crystallisation of sources from solution decreases the entropy?

Answer 1

However, as said by others, this is compensated by an increase of the entropy of the room the furnace is in. Probably, you are missing the latent heat impact on the entropy. The latent heat release increasesthe entropy of the liquid/vapor and overrides the decrease of entropydue to crystallization/condensation.

Answer 2

Hii friend,

# Answer- No, entropy of universe increases in crystallization.

# Reason -
- During crystallization, the sources from solution change from aqueous to solid state, hence entropy of the crystal decreases.
- But it's an open system and so release of heat of fusion increases the entropy of vapor and overrides the decrease of entropy due to crystallisation.
- So overall entropy of the universe is increased during crystallisation.
