    If we are being really pedantic, the freezing and boiling part of first paragraph is only true under sea level atmospheric pressure, so technically, you can’t really relate these quantities with the given information in the first paragraph either.

    But I don’t think that’s the point this exerpt is trying to make.

      Unless stated otherwise, you always just assume 1atm of pressure.

        Yeah but if you’re boiling your pasta and you live a few thousand feet above sea level you’re gonna want to give it a bit more time since water boils colder up here.

          ~Who the hell times how long their pasta takes to boil? You just go until it starts making noises.~

          Edit: woopsie…that’s not what they said. Colder - so it takes longer for the pasta to cook. My bad.

              Oh yeah…thanks for pointing that out. I’ve been fighting some nasty cold/flu/covid thing and clearly not reading straight haha.

        A calorie is not a metric unit but the joule is, 1 calorie is approximately 4.2 joule. A gram of hydrogen does not exactly have 1 mole of particles. The historical definition for the mole was the count of atoms in 12 grams of the ¹²C carbon isotope, which is slightly different.

          The historical definition for a mole is a little underground mammal. Then you science geeks decided to just screw it all up because you couldn’t be bothered to make your own word. A molar’s a mole tooth, dangert!

      A pressure which, funnilly enough, is not in fact 1 bar (as one would expect) in the metric system but rather 1.013 bar.
