At room temperature hydrogen is a gas. It is a colorless, tasteless and odorless gas. It is the lightest gas. It is insoluble in water. It is highly inflammable and burns with blue flame forming water. Liquefication temperature of hydrogen is -252oC. Bond energy of H-H is 431 Kj/mole. Electro negativity of hydrogen is 2.1.
The spectra contain two regions of interest - the first at around room temperature where there is desorption of hydrogen (m/z = 2) alone, and the second between 400 K and 500 K, where there are coincident desorption peaks attributable to hydrogen and carbon dioxide (m/z = 44).
