Rate of Evaporation
In this classic experiment, from the Royal Society of Chemistry, students investigate factors affecting evaporation. Using propanone on microscope slides, students change the conditions and time how long it takes for the propanone to evaporate. An explanation of a teacher demonstration using data logging apparatus is also given.
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: evaporation, change of state, sweating, kinetic theory.
