Additional or Chemistry ISA CU 2.2 Topic of investigation Section C2.5.1b: An exothermic reaction is one that transfers energy to the surroundings. Examples of exothermic reactions include combustion, many oxidation reactions and neutralisation. Everyday uses of exothermic reactions include self-heating cans (eg for coffee) and hand warmers. What could affect the change in temperature? INDEPENDENT VARIABLE

Planning Investigation You must plan an investigation to consider one factor that would affect the change in temperature of an exothermic reaction. 1.Read Sources A-E 2.Select two sources to complete your planning sheet
