The task is related to the energy balance during the transition between the states of aggregation, and it specifically addresses the cooling of indoor air through the evaporation of water from damp towels.
Degree of difficulty of the task: low to medium.
The teaching methods provide teachers with all the important information on using the worksheet of the same name and the related incremental hints in class. The scientific background on the task and possible variations are provided.
The five or six incremental hints for the task are provided with the corresponding answers. They are also available as a separate ready-to-print medium named “Can wet towels reduce heat? (hints for printing, version with experiment)” and “Can wet towels reduce heat? (hints for printing)” or as interactive media “Can wet towels reduce heat? (interactive hints, version with experiment)” and “Can wet towels reduce heat? (interactive hints)” on the media portal of the Siemens Stiftung.
