Burning Money

               A combustion reaction occurs between alcohol and oxygen producing heat, light, carbon dioxide and water. Rupee not is soaked an alcohol water solution, the alcohol has a high vapour pressure and is mainly on the out side of the material. when the rupee is lit the alcohol is what actually burn ? The temperature at which the alcohol burns is not high enough to evaporate the water which has a high specific heat so the rupee remains wet and isn't able to catch fire on its won.

                   After alcohol burned, the flame goes out.


  • Mix 50 ml of water with 50 ml 100% pure alcohol.
  • Add a pinch of salt to the solution
  • Soak a rupee into the solution, that it is thoroughly wet.
  • Use tongs to pick up the rupee.
  • Allow any excess liquid to drain it.
  • Move the rupee away from the solution.
  • Light the rupee on fire and allow it to burn until the flame goes out.
  • Alcohol has high vapour pressure. So alcohol easily catch fire and burns quickly.
  • But the temperature not enough to the water. so the rupee remains wet. Isn't able to catch the fire.
