Hydrogen specific heat
WebOne problem I faced was determining the specific heat capacity of the hydrogen at higher temperatures. As found here, the heat capacity increases with temperature. I used the value at 250 °K, so the number I calculated might be lower limit of the correct value. Web26 feb. 2015 · Hydrogen bonding in water is far too weak to be compared with intramolecular bonds like covalent or ionic bonds, but it's strong enough that to be broken, it will require lots of energy. That's why water boils at 100 ° C. Many know the reason of water's high specific heat to be hydrogen bonding.
