  • Exothermic and Endothermic Reactions
    • Exothermic
      • Transfer energy into the surroundings
        • Makes surroundings cooler
      • Examples Are combustion, oxidation and neutralisation
      • Used in hand warmers and Self Heating cans.
    • Endothermic
      • Take energy from the suroundings
        • Making surroundings cooler
      • Electrolysis, thermal decomposition and ethnolic acid and sodium carbonate
      • Cold Packs
    • When a reaction is reversible, one side is exothemic and the other is Endothermic
      • hydrated copper sulfate (blue)«». anhydrous copper sulfate (white) + water
  • Used in hand warmers and Self Heating cans.



exothermic makes surroundings warmer, not cooler
