High heating value of h2

WebHydrogen is the lightest and most abundant element in the universe. Specific heat of Hydrogen Gas - H2 - at temperatures ranging 175 - 6000 K: The values above apply to undissociated states. At high temperatures above 1500 K dissociation becomes appreciable and pressure is a significant variable.
