Answer 4

addition of a non-volatile solute decreases the vapor pressure of the solution compared to the pure solvent, which can be defined by Rauolt's Law: \(P = P_Ax_A+P_Bx_B+...\). You might ask why? Well, it's because the solvent is the one actually interacting with the solvent molecules. Which is in turn related to the freezing point. I don't know if you've heard but this is the reason some people put salt on their roads after a heavy snow. To keep the snow from refreezing!
The boiling point effect is that temperature where the vapor pressure of the solution equals atmospheric pressure. If the vapor pressure of the solution is lower than the solvent, then a higher temperature will be required to raise the vapor pressure of the solution to its boiling point. (important)
Freezing point has to do with entropy. The entropy of the solvent in a solution is higher than the entropy of the same pure solvent.

Read the colligative properties :)

Okayy thank you!
