Boiling point liquid is the highest temperature (and pressure) it will actually boil at. See also Vapour pressure of water. The element with the lowest boiling point is helium. Both the boiling points of rhenium and tungsten exceed 5000 K at standard pressure; because it is difficult to measure extreme temperatures precisely without bias, both have been cited in the literature as having the higher boiling point. As can be seen from the above plot of the logarithm of the vapor pressure vs. the temperature for any given pure chemical compound, its normal boiling point can serve as an indication of that
Stone boiling Stone boiling Stone boiling is a moist-heat cooking method. It involves placing heated rocks into a water-filled container to heat the liquid to the point where it can be used to cook. This method of food preparation is a fuel-intensive process and it often requires the heating and reheating of stones before the water reaches an effective cooking temperature. Indigenous peoples in what is now Canada and the United States of America, especially on the West and Northwest Coast, used stone boiling. Cooking this way allowed for a more controlled temperature which made the extraction of fats and oils easier
