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.
- Pour 200 ml of hydrogen peroxide into a beaker.
- Insert the thermometer and look at the temperature.
- Add some yeast, not too little, stir it into the hydrogen peroxide.
- 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 🙂

That’s good to know your WP followers have got your back Dan. 🙂
Thanks for worrying about me 🙂 Other people are also worried about me too.
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!)
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.
That’s a very significant temperature change. Surprising!
Also that you start off at 34C – that’s a hot day!
