Energy Transfer in Reactions
  1. Exothermic Reaction
    1. an EXOTHERMIC REACTION is one which TRANSFERS ENERGY to the surroundings, usually in the form of HEAT and usually shown by a RISE IN TEMPERATURE
      1. an example of an exothermic reaction is hand warmers, they use the oxidation of iron in air to generate heat
    2. Endothermic Reaction
      1. an ENDOTHERMIC REACTION is one which TAKES IN ENERGY from the surroundings usually in the form of HEAT and is usually shown by a FALL IN TEMPERATURE
        1. an example of an endothermic reaction in everyday life is sports injury packs, they take in heat and the pack becomes very cold
      2. Reversible Reactions can be both exothermic and endothermic
        1. if the reaction is endothermic in one direction, it will be exothermic in the other
