Question

How can boiling point of a liquid can be raised without adding any soluble impurities? Give suitable examples with an activity

Answer 1

Explanation:

Great Questions! Many people would not know but liquids, including the humble water actually boils not due to the fact that we heat it but actually because when you heat water or any other liquid, it's pressure vis-a-vis atmospheric pressure changes.

In order to raise the boiling point of a liquid without adding anything in it, we can increase the pressure around the liquid, this can delay the boiling of the liquid and elevate the boiling point.

This is why in hill stations, it takes longer to cook or boil water, because the atmospheric pressure there is higher
