How to reference this medium
The materials supplied allow eight groups of students to conduct the experiments simultaneously. If all subexperiments are conducted in the sequence below, they can be used to complement a learning unit on evaporation heat and “evaporative cooling." This provides a good basis for further study of general thermodynamics down to the particle level.
The experiment comprises two subexperiments:
• Why do you freeze in wet clothing?
• How does a wet cotton pad cool you?
Notes:
• Observe the safety information in the instructions as well as the applicable safety guidelines for your school.
• All materials mentioned in the instructions will have to be purchased directly from commercial sources.
