Exothermic Iron-Oxide and Aluminum Reaction http://www.FreeScienceLectures.com A metal crucible is filled with iron-oxide and aluminum. A small amount of potassium, sugar and chloride is placed on top of iron-oxide aluminum mixture. A few drops of concentrated sulphuric acide is added to the mixture to start the reaction. The reaction extremely exothermic. The crucible becomes red hot. The aluminum has reduced the iron-oxide to iron. --- It's Never too Late to Study: http://www.FreeScienceLectures.com --- Notice: This video is copyright by its respectful owners.

Endothermic & Exothermic Electric Discharges Everyone knows that electricity can be used to generate heat. What most people don't know is that electricity can also be used to generate cold. These two reactions are called exothermic and endothermic. Exothermic means energy is radiated outward. Which usually generates heat or heating. Endothermic means energy is radiated inward which usually generates cold or cooling. Both effects have a distinct sound when done rapidly. Exothermic will have a loud snap or bang. This is because the reaction forces air and energy away from the point of discharge, making a temporary vacuum which is then quickly filled in by the surrounding air, creating a snapping sound. Endothermic however does not make a loud snap or bang. This is because the reaction absorbs energy around it. This makes a ping sound, like when you hit a piece of hollow medal with a vacuum inside. Endothermic discharges are also hard to capture on camera because some of the photons from the discharge are quickly absorbed into the vacuum.

Dialog # 0.10 : Is Hell Exothermic? Charlie McNickel has borrowed this thesis, reportedly an actual essay turned in to a teacher. I've no idea who the originating student was, but thanks to him, Charlie and I are having a little fun with the ideas. Rated G.
