Because of its excellent combustion characteristics and regenerative cooling capability, hydrogen is also being considered as a fuel in future air-breathing hypersonic vehicles. Hydrogen has several disadvantages which tend to offset, to a certain extent, its advantages. Two of its major disadvantages ...
The heat capacity of 99.8% pure hydrogen fluoride has been measured between 15 and 300°K. No transitions were found, in the solid, as is the case in the other hydrogen halides; this is probably due to the existence of hydrogen bonding in hydrogen fluoride. The heat of fusion at the mel...

4it will only be included here in its briefest outline. It relies on the difference in the ability to scatter neurons elastically between hydrogen anddeuterium. This raised the expectation that by mixing a small amount of deuterated material (guests) with a largely hydrogen containing (host) ...

The heat of vaporization of water is quite high because of the strong hydrogen bonds that hold the water molecules together. The heat of vaporization of water is 2260 J/g. 2260 Joules is required to evaporate one gram of water. What is the heat of vaporization in chemistry? It is the en...
