Learners examine how the boiling point increases with increasing pressure. An example from industry is given.

The definition of an isotope is illustrated using the three isotopes of carbon. The three isotopes of hydrogen are discussed as exceptions.

Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.

Learners examine phase diagrams that show the phases of solid, liquid, and gas as well as the triple point and critical point.
