Boil water in a pan. Keep on boiling until all the water in the pan has evaporated. What do you observe in a pan and why?

Answer 1

• When we heat water in a pan, it begins to boil after some time.
• If we continue to heat further, the quantity of water in the pan begins to decrease.
• All the water in the pan evaporates after some time.
• We observe that there will remain some suspended impurities that are present in the water earlier.
