Product Description

By: The Flinn Staff

It seems counterintuitive—when freezing weather is predicted, orange growers spray the trees with water to prevent the fruit from freezing! The water actually releases heat when it solidifies. The purpose of this experiment is to investigate the solid–liquid phase changes for an unknown organic solid and determine the energy changes that take place when a solid melts or a liquid freezes. Students measure the heating and cooling curves for the solid and identify the unknown based on its melting point. Kit contains three low-melting organic “unknowns” and borosilicate glass test tubes. Reproducible student handouts, detailed background information, complete Teacher Notes with sample data and answers to all questions, and all chemicals and consumable supplies needed to perform the lab are provided.

Complete for 30 students working in pairs. Fifteen digital thermometers are recommended and available separately.
