Boiling and Vaporization

Postby Sujin Lim 1H » Fri Jan 28, 2022 12:28 am

Would it be correct to say that boiling water and water vaporizing is the same thing? So if a question asks how much heat is required to boil water at 100 deg Celsius, would we just be using the deltaH for vaporization and multiplying that value by the number of moles of the water present?

Vaporization describes the phase change from a liquid to a vapor/gas. Boiling is a method in getting a substance to undergo vaporization. Unlike evaporation, boiling doesn't happen just at the surface, whereas evaporation happens only at the surface. I think in this class there would be no need to differentiate between vaporization and boiling, so I personally believe we would just use deltaH for vaporization like you described!

Yes. You would just multiply deltaH of vaporization by the amount of moles of the water being vaporized.

Yes,
Boiling is the process of vaporization.

Hi, Vaporization includes both boiling and evaporation. Boiling refers to what happens to the liquid when the temperature reaches the boiling point and evaporation could happen without reaching the boiling point temperature.

yeah you are right about that
