Moreover, why there is no oxygen in the space?
In space, there is very little breathable oxygen. A ground-based experiment by an experimental astrophysicist at Syracuse University found that oxygen atoms cling tightly to stardust. This prevents the oxygen atoms from joining together to form oxygen molecules. Where can Helium-3 be found on Earth? The abundance of helium-3 is thought to be greater on the Moon than on Earth, having been embedded in the upper layer of regolith by the solar wind over billions of years, though still lower in abundance than in the Solar System's gas giants.
Does nuclear fusion make helium?
In nuclear fusion, you get energy when two atoms join together to form one. In a fusion reactor, hydrogen atoms come together to form helium atoms, neutrons and vast amounts of energy. It's the same type of reaction that powers hydrogen bombs and the sun. Which gas is used in fridge? Modern refrigerators usually use a refrigerant called HFC-134a (1,1,1,2-Tetrafluoroethane), which does not deplete the ozone layer, unlike Freon.
Consequently, are refrigerants flammable?
Refrigerant History Nearly all of the historically used refrigerants were flammable, toxic, or both. Some were also highly reactive, resulting in accidents (e. g., leak, explosion) due to equipment failure, poor maintenance, or human error. How do you make liquid nitrogen?
