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.
  2. Insert the thermometer and look at the temperature.
  3. Add some yeast, not too little, stir it into the hydrogen peroxide.
  4. Keep waiting, the temperature will be high.

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 🙂

  1. That’s good to know your WP followers have got your back Dan. 🙂

  2. It was Once 40C here in Cape Town – so I agree – far too hot!
    I look forward to seeing your post – just be very careful with those hot temps! (I’m sure you are!)

  3. Yes, Asia is hot, one day it was even 40C! I had a tough time that day… I’ve another experiment that can go even hotter. It can go up to about 70C! Just keep waiting, and I’ll probably going to post it.

  4. That’s a very significant temperature change. Surprising!
    Also that you start off at 34C – that’s a hot day!
