Sentences with phrase «oxygen gases over»

Not exact matches

Scientists have converted a gentle flow of gas directly into an electric current by flowing common gases like oxygen, nitrogen, or argon over a special kind of semiconductor.

«Measuring the oxygen content of galaxies over cosmic time is one of the key methods we have for understanding how galaxies grow, as well as how they spew out gas into the intergalactic medium,» she said.

The still slightly burning superheated exhaust gasses from too much oxygen in the AFR from incorrect carburetor settings slowly overheated his valves and they deteriorated over time until they began to even crack a bit.

Almost immediately (nanoseconds) they relax from their excited state by either 1) emitting that energy as a new photon, some of which will continue up towards space, some of which will go back downward to be reabsorbed, thus keeping the energy in the atmosphere longer, or 2) by colliding with another gas molecule, most likely an O2 (oxygen) or N2 (nitrogen) molecule since they make up over 98 % of the atmosphere, thereby converting the extra vibrational energy into kinetic energy by transferring it to the other gas molecule, which will then collide with other molecules, and so on, making the air warmer.

So unless there is a permanent, drastic, progressive and one - way alteration in the chemical makeup of the oceans over geological epochs (which would entail the massive evolution of hydrogen gas and the production of oxygen, chlorine or hydrogen peroxide) or a similarly huge increase in its potential energy (levitating it off the ocean floor), the energy involved will still have to be dissipated as heat (there's nowhere else for it to go, unless you get all science - fictiony and assume it vanishes into hyperspace or turns into neutrinos or something).

31) Despite activist concerns over CO2 levels, rising CO2 levels of some so - called «greenhouse gases» may be contributing to higher oxygen levels and global cooling, not warming

Because the atmosphere is a Nitrogen - Oxygen based atmosphere, representing over 99.9 % of the atmosphere's gasses, adding Carbon Dioxide to the atmosphere cools the Nitrogen - Oxygen based atmosphere, as demonstrated in experimental designs conducted by Professor Gert Venter, Agricultural Engineering, University of Pretoria: «You know, that's why all I can do is laugh when these global warming monkeys tell me that CO2 is a greenhouse gas.
