An equation is derived which describes the non-isothermal mass-loss kinetics of a deaquation reaction which occurs near the boiling point of water. The equation is tested using published experimental mass-loss data for the deaquation of BaCl 2·2H 2O and BaBr 2·2H 2O....

Antifreeze has a high boiling point, boiling point of water is 100 ℃, high-quality antifreeze boiling point usually above 106 ℃. Force the use of ethylene glycol antifreeze systems quality formulations to meet the requirements of different freezing and boiling points. If you do not use antifree...
At first, this would have had little effect on the oceans of Venus. Although the temperature would have climbed above 100° C, the boiling point of water at sea level on Earth, the added atmospheric pressure from water vapor would have kept the water in Venus’ oceans in the liquid state...

So, why have most of us been taught that the boiling point of water is constant? And, if it is not constant, how can it be used as a 'fixed point' for the calibration of thermometers? History of science has the answers.关键词:...
could have been hotter than the boiling point of water today.However, life as we know it is quite sensitive to temperature, and no modern organisms are known to survive much above 100℃.It is unlikely that life became established until surface temperatures had decreased to this level, or ...
