When the Kitchen Turns into a Physical Chemistry Lab

We present our experience with transferring a fourday photometry and dye-adsorption laboratory experiment to the kitchens of students of Applied Thermodynamics from our degree in “Industrial Chemical Process Engineering”. The students designed and built a double-beam photometer using their smartphon...
