Item #: PF2002
In this lab experience, students experience on how energy flows in chemical reactions by exploring endothermic and exothermic reations. Students observe reacting CaO with H2O will result in a transfer of energy from a system (the reaction) to the surroundings (the area in direct proximity to the reaction) that results in a measurable increase in temperature. Reacting NH4SCN and Ba(OH)2•8H2O will result in a transfer of energy from the surroundings to the system that results in a measurable decrease in temperature.
