Warm Chemistry

Warm Chemistry

After that long break, I would like to do a very simple experiment to start. This one is pretty common, most people probably know this experiment, but no one realized that there was more to it.

Things you’ll need: Yeast, hydrogen peroxide, a beaker, and a thermometer.

  1. Pour 200 ml of hydrogen peroxide into a beaker.IMG_20140101_070545
  2. Insert the thermometer and look at the temperature.IMG_20140101_070613
  3. Add some yeast, not too little, stir it into the hydrogen peroxide.IMG_20140101_070705
  4. Keep waiting, the temperature will be high.IMG_20140101_070056

My temperature is about 63°C. That’s very hot. You saw the temperature change. The energy in the chemicals was converted to heat energy by the chemical change. You must know the yeast + H2O2 reaction, so I’m not going to explain it. This is also another way to create the elephant’s toothpaste demonstration.

Thanks for taking your time to look at this post 🙂
