Description
Students investigate the thermodynamics of physical and chemical changes that absorb and release heat energy with this 2-activity kit. They calculate the heats of solution of 2 salt compounds and determine the heat of combustion of a hydrocarbon. For both activities, students write balanced thermochemical equations for the reactions and classify them as endothermic or exothermic. Kit activities take about 45 min. Kit materials are sufficient for a 30-student class. Value Kit equips 4 classes!
Grades 9–12. Heat up your study of thermodynamics with this 2-activity kit. Students will investigate the thermodynamics of physical and chemical changes that absorb and release heat energy. Using a coffee cup calorimeter, students calculate the heats of solution of 2 salt compounds. In the second activity, students determine the heat of combustion of a hydrocarbon using a soda can calorimeter. For both activities, students will write balanced thermochemical equations for the reactions and classify them as endothermic or exothermic. Kit activities require approximately 45 min. Kit materials are sufficient for a class of 30 students working in groups of 3. Value Kit includes materials for 4 classes!
