Sentence examples for conversion of hydrogen from inspiring English sources
The energy radiated by the Sun is produced during the conversion of hydrogen (H) atoms to helium (He).
As stars evolve, however, the conversion of hydrogen into helium is followed by the conversion of helium into heavier elements.
For the Sun and other normal main-sequence stars, the source of energy lies in the conversion of hydrogen to helium.
In 1937 German physicist Carl Friedrich von Weizsäcker discovered the CNO cycle, in which carbon, nitrogen, and oxygen act as catalysts in a sequence of nuclear reactions that leads to the conversion of hydrogen into helium.
Perhaps the most important examples are the conversion of hydrogen to helium in the centre of stars, such as the Sun, and during thermonuclear reactions used in atomic bombs.
At all stages in a star's evolution there will be a region where the temperature is suitable for the conversion of hydrogen into helium, but it appears that there will be only a thin shell of helium separating the regions in which hydrogen has not yet been converted into helium and the region where helium has been burned into heavy elements.
Proton exchange membrane fuel cells are uniquely placed as the key technology for the successful conversion of hydrogen-containing fuels to electricity and heat.
