I have been putting together some videos for the online classes that I will be teaching in the fall, and I just posted this one to YouTube. It demonstrates the true definition of boiling point, and it shows how you can freeze a liquid by boiling it. It also demonstrates what the triple point is.
This brings to mind an old Burns and Allen gag where Gracie was boiling water and putting it in the freezer. George asked what she was doing and she replied that she was freezing boiling water so when she needed it all she had to do was thaw it out.
Now THAT is funny!
Fascinating experiment, Dr. Jay! Thank you for the chemistry/physics class.
