Question

The boiling point of a liquid _______ by the addition of soluble impurities to it.

• A. decreases
• B. increases
• C. remains the same
• D. varies randomly

Answer 1

The correct option is B increases

If an impurity like common salt, is added to water, it boils at a temperature higher than $100{}^{\circ }\text{C}$. This is reason behind the addition of salt water to provide sufficient heat energy to its contents before boiling, so the cooking becomes easier and more efficient.
