classification?
2. Which facts should be kept in mind while making a cooking utensil?
3. Why is a separating funnel used to separate a mixture of oil and water?
Answers
1. To be satisfactory, a utensil should be without seams or curved edges, because it is difficult to remove particles of food that collect in such places. A vessel that is hard to wash should be avoided, and one that will tip easily is not desirable, either.
2. Two immiscible liquids, oil and water, can be separated by using Separating Funnel. The mixture of oil and water forms two separate layers because they are completely insoluble in each other. Oil forms the upper layer while water forms lower.
I hope my answer helps you....✌
