5. Frequently Asked Questions (FAQ)

Q1: What is molar enthalpy of vaporization?
A: It's the energy required to vaporize one mole of a substance at its boiling point under standard pressure.

Q2: How is boiling point elevation measured?
A: It's the difference between the boiling point of the solution and the pure solvent.

Q3: Why does osmotic pressure matter?
A: It's critical for understanding processes like water purification, biological cell function, and drug delivery systems.
