Demonstration: Cooking an Egg in Chemistry Class
In this demonstration, students will observe the very high latent heat of vaporization for water by boiling water over a Bunsen burner in a paper cup to cook a boiled egg. The discussion can be extended to incorporate intermolecular forces to explain the unusually high boiling point of water, as well as heat of vaporization and specific heat capacity.

Activity: Simulation Activity: Heating Curve of Water
In this simulation, students will investigate qualitatively and quantitatively what happens as water changes states.

Intermolecular Forces, Polarity, Molar Mass, Intermolecular Forces, Boiling Point, Heat of Vaporization | High School
Lab: Heat of Vaporization
In this lab, students test whether a substance’s heat of vaporization is determined by its molar mass, the strength of its intermolecular forces, or both.

Simulation: Heating Curve of Water
In the May 2015 issue, students explore the heating curve for water from a qualitative and quantitative perspective. Students compare illustrations of each physical state depicted on the curve and calculate the energy required to transition from one state to another.
