What is Measuring Urea Dissolution Entropy about?

This document describes a simplified laboratory experiment for measuring the entropy change of urea dissolution for introductory chemistry students. The authors modified an existing procedure to make it more pedagogically simple by having students directly determine the concentration of urea in a saturated solution using a graduated cylinder, rather than using more complex techniques. Students are guided through determining the enthalpy, entropy and free energy changes of the dissolution process. The result
