Melting and Freezing
In this classic experiment, from the Royal Society of Chemistry, students heat stearic acid and observe the temperature changes that occur during melting. The stearic acid is also cooled and observations of temperature changes during solidifying are made.
The resource is set out as teachers' notes followed by the students' page which presents the task to be investigated. A list of apparatus and chemicals needed for the investigation is provided, together with teaching tips.
Curriculum links include: change of state, particle model, heating curve, cooing curve.
