Answer 2

Dear Student,

◆ Answer -

(C) Formation of clouds

● Explanation -

• In physical change, composition of substances remains same after.
• In chemical change, composition of substance changes.
• During formation of clouds water vapour condenses to form clouds but its composition doesn't change. Hence, this is physical change and not a chemical change.
• In all other examples, i.e. baking of cake, ripening of fruits, rancidity of butter their actual chemical composition changes. Hence, they are chemical changes.

Thanks dear. Hope this helps you...
