  2. Oxygen equivalent - Wikipedia

    en.wikipedia.org/wiki/Oxygen_Equivalent

    Oxygen equivalent compares the relative amount of oxygen available for respiration at a variable pressure to that available at SATP.As external respiration depends on the exchange of gases due to partial pressures across a semipermeable membrane and normally occurs at SATP, an oxygen equivalent may aid in recognizing and managing variable oxygen availability during procedures such as ...

  7. Oxygen compatibility - Wikipedia

    en.wikipedia.org/wiki/Oxygen_compatibility

    In an oxygen system the presence of oxygen is implied, and in a sufficiently high partial pressure of oxygen, most materials can be considered fuel. Potential ignition sources are present in almost all oxygen systems, but fire hazards can be mitigated by controlling the risk factors associated with the oxygen, fuel, or heat, which can limit the ...

  8. Copper - Wikipedia

    en.wikipedia.org/wiki/Copper

    Copper is also found in many superoxide dismutases, proteins that catalyze the decomposition of superoxides by converting it (by disproportionation) to oxygen and hydrogen peroxide: Cu 2+-SOD + O 2 − → Cu +-SOD + O 2 (reduction of copper; oxidation of superoxide) Cu +-SOD + O 2 − + 2H + → Cu 2+-SOD + H 2 O 2 (oxidation of copper ...

  9. Table of specific heat capacities - Wikipedia

    en.wikipedia.org/wiki/Table_of_specific_heat...

    For gases, departure from 3 R per mole of atoms is generally due to two factors: (1) failure of the higher quantum-energy-spaced vibration modes in gas molecules to be excited at room temperature, and (2) loss of potential energy degree of freedom for small gas molecules, simply because most of their atoms are not bonded maximally in space to ...
