What happens to the boiling point of water when salt is added?

When salt is added to the water, its boiling point is enhanced as compared to the normal boiling point. 

Although the difference between the new and previous boiling points is not much, it does increase. Like after adding twenty grams of salt in five liters of water, there is a change in boiling point from 100 degrees centigrade to 100.04 degrees centigrade.

Why is there an increase in the boiling point of water after salt is added?

The reason behind the increase in the boiling point of water after adding salt is that for water to boil, there is a requirement that the vapor pressure of water must be the same as the pressure of the atmosphere. 

After the addition of salt, water molecules find it difficult to escape from the pot and enter into the gas phase. This is the requirement of the water before boiling. Due to this, a higher boiling point is noticed in the presence of salt.
