Exothermic and endothermic reactions

What this topic asks you to be able to do

  • state that an exothermic reaction gives off thermal energy to its surroundings, so the surroundings become warmer
  • State that neutralisation and combustion both fall into the exothermic category.
  • state that an endothermic reaction takes in thermal energy from its surroundings, so the surroundings become cooler
  • state that the dissolving of ammonium nitrate and cracking both count as endothermic reactions
  • Interpret data, including graphs, that record how temperatures shift during endothermic and exothermic reactions.
