Answer #1

Simply, by interactions between solvent and solute.....i.e. so-called colligative properties...

Explanation:

The dissolution of a solute in a solvent relies on the interaction between solute particles, and solvent molecules....and usually this is an attractive force. It is reasonable that such interactions should ELEVATE the boiling point of a solution by an amount proportional to the concentration of the dissolved solute..
