a) Filtration, physical change
b) Crystallization, chemical change
c) Crystallization, physical change
d) Condensation, chemical change

Answer 1

Answer:

(c) Crystallization, physical change

Explanation:

Its obvious from the line "After some time crystals of copper sulphate can be seen" dat copper crystals are obtained any process involving formation of crystals is crystallisation. Crystallisation is a physical change.
