What is the primary reason for the elevation of boiling point in a solution?

Step 1: Understand that boiling point is the temperature at which a liquid turns into vapor.
Step 2: Know that a solution is made up of a solvent (like water) and a solute (like salt or sugar).
Step 3: Realize that when you add a solute to a solvent, it changes how the solvent behaves.
Step 4: Learn that the presence of the solute lowers the vapor pressure of the solvent.
Step 5: Understand that lower vapor pressure means the solvent needs to be heated to a higher temperature to boil.
Step 6: Conclude that this is why the boiling point of the solution is higher than that of the pure solvent.
