  • where’s this “freezing water” you can stick your thermometer into, that’s reliably == 0 degrees? Ice keeps getting colder, and melted water can be any temperature above 0.

    A substance undergoing phase change will hold its temperature until the change is complete. That means that once water starts freezing, it will be 0°C until it is all ice. Same goes for ice thawing. Yes only pure H2O will freeze at exactly 0°, but unless you deliberately put some shit in it it will be very, very, very close. Boiling is a bit more sensitive, but still a lot less than the natural variance between body temperatures in normal conditions.

    You’re taking the procedure literally, but it was just to get a point across. Also, using the freezing and water boiling points of water was used to define Fahrenheit too for most of the 20th century.
