Episode 7 — Physical Properties of Matter

Boiling and Melting Points of Different Materials

Learners will be able to:

• Compare the boiling points and melting points of different substances (water, nitrogen, ethanol) using a graph • Interpret (analyse) data presented on a graph to determine the physical state of a substance at a given temperature, such as room temperature • Use boiling point data to predict and explain which of two liquids in a mixture will boil first
