Hey everyone,
I found this video on Youtube of this guy boiling water by reducing the pressure:
I'm not sure how the gauge he's looking at works but I think this is the vacuum instrument he's using: https://us.vwr.com/store/catalog/product.jsp?product_id=4789427
^It says that it provides vacuum to 723.9mm Hg.
I looked at a water phase diagram and noticed that you could only have 1kPa (7.5mm Hg) of pressure at 25C to make water evaporate.
In conclusion, I don't really understand how his water is managing to boil and was wondering if any of you knew why.
