Hydrogen is the primary component of Jupiter and the other gas giant planets.Īt some depth in the planet's interior the pressure is so great that solid Tritium is readily produced in nuclear reactors and is used in the production of the Its melting point is only 20 degrees above absolute zero. Liquid hydrogen is important in cryogenics and in the study of superconductivity, as displacement from acids by certain metals.reaction of sodium or potassium hydroxide on.decomposition of certain hydrocarbons with heat,.alone amounts to about 3 billion cubic feet per Stellar hydrogen fusion processes release massive amounts of energy by combining In powering the universe through both the proton-proton reaction and carbon-nitrogen cycle. The mass of the universe! This element is found in the stars, and plays an important part Hydrogen is estimated to make up more than 90% of all the atoms - three quarters of Heavier elements were originally made from hydrogen atoms or from other elements that were Hydrogen is the most abundant of all elements in the universe.
