About this topic

Revise energetics, including energy changes when substances change state, exothermic and endothermic reactions, and what happens to the surroundings in each.

This topic covers

energy changes on melting, boiling and freezing
exothermic reactions and their effect on the surroundings
endothermic reactions and their effect on the surroundings
recognising a reaction type from a temperature change

Example question types

classify a reaction as exothermic or endothermic
state what happens to the temperature of the surroundings
identify the energy change in a change of state
