Hydrogen specific heat
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. Web11 nov. 2024 · The high heat capacity of seawater has been cited as why 93% of the heat trapped by anthropogenic greenhouse gases is absorbed by the ocean. Specific heats (C P) are closely tied to molecular weight.The mean molecular weight of pure water over the range 0–40 °C is 86.1–80.7 and 89.4–84.5 for seawater.

Web12 apr. 2024 · Polythionic acid stress corrosion cracking (PASCC) occurs in certain materials, such as austenitic stainless steel, under specific environmental conditions. It is caused by the interaction of the ... 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.
WebSpecific heat, heat of vaporization, and density of water: Water has a high heat capacity and heat of vaporization, and ice—solid water—is less dense than liquid water. Water owes these unique properties to the polarity of its molecules and, specifically, to their ability to form hydrogen bonds with each other and with other molecules.
