WebHeat cannot transfer energy spontaneously from colder to hotter, because the entropy of the overall system would decrease. Suppose we mix equal masses of water that are originally at two different temperatures, say 20.0 °C 20.0 °C and 40.0 °C 40.0 °C. The result will be water at an intermediate temperature of 30.0 °C 30.0 °C.

WebHappy little cook Club of lovers of delicious food Menu. Menu WebSo when water boils at 100 C at 1 atm, this means that only at 100 C does the vapour pressure of the water overcome the external vapour pressure. If you increase the external pressure to 2 atm, the water requires more energy to be able to overcome this pressure, therefore boiling point increases. this is how it works.
