How can you measure a temperature change?
1~ put a polystyrene cup into a large beaker of cotton
2~add a known volume of your reagent to the cup
3~measure the initial temperature of the solution
4~add a measured mass/volume of your second regeant and stir the reaction mixture
5~put a lid onto to reduce energy loss via evaporation
6~record the temperature after a set amount of time
7~calculate temperature change
