  2. 2,5-Dichlorophenol - Wikipedia

    en.wikipedia.org/wiki/2,5-dichlorophenol

    2,5-Dichlorophenol (2,5-DCP) is a chlorinated derivative of phenol with the molecular formula Cl 2 C 6 H 3 OH. References. Cited sources. Haynes, William M., ed ...

  3. Compressibility factor - Wikipedia

    en.wikipedia.org/wiki/Compressibility_factor

    For a gas that is a mixture of two or more pure gases (air or natural gas, for example), the gas composition must be known before compressibility can be calculated. Alternatively, the compressibility factor for specific gases can be read from generalized compressibility charts [ 1 ] that plot Z {\displaystyle Z} as a function of pressure at ...

    A Assuming an altitude of 194 metres above mean sea level (the worldwide median altitude of human habitation), an indoor temperature of 23 °C, a dewpoint of 9 °C (40.85% relative humidity), and 760 mmHg sea level–corrected barometric pressure (molar water vapor content = 1.16%).

  5. Real gas - Wikipedia

    en.wikipedia.org/wiki/Real_gas

    Where p is the pressure, T is the temperature, R the ideal gas constant, and V m the molar volume. a and b are parameters that are determined empirically for each gas, but are sometimes estimated from their critical temperature ( T c ) and critical pressure ( p c ) using these relations:

  6. Standard temperature and pressure - Wikipedia

    en.wikipedia.org/wiki/Standard_temperature_and...

    The relationship between the two constants is R s = R / m, where m is the molecular mass of the gas. The US Standard Atmosphere (USSA) uses 8.31432 m 3 ·Pa/(mol·K) as the value of R. However, the USSA in 1976 does recognize that this value is not consistent with the values of the Avogadro constant and the Boltzmann constant. [49]

  7. Molar heat capacity - Wikipedia

    en.wikipedia.org/wiki/Molar_heat_capacity

    In other words, that theory predicts that the molar heat capacity at constant volume c V,m of all monatomic gases will be the same; specifically, c V,m = ⁠ 3 / 2 ⁠ R. where R is the ideal gas constant, about 8.31446 J⋅K −1 ⋅mol −1 (which is the product of the Boltzmann constant k B and the Avogadro constant).

  8. Redlich–Kwong equation of state - Wikipedia

    en.wikipedia.org/wiki/Redlich–Kwong_equation_of...

    p is the gas pressure; R is the gas constant, T is temperature, V m is the molar volume (V/n), a is a constant that corrects for attractive potential of molecules, and; b is a constant that corrects for volume. The constants are different depending on which gas is being analyzed. The constants can be calculated from the critical point data of ...

  9. Polychlorinated biphenyl - Wikipedia

    en.wikipedia.org/wiki/Polychlorinated_biphenyl

    PCB warning label on a power transformer known to contain PCBs. Polychlorinated biphenyls (PCBs) are organochlorine compounds with the formula C 12 H 10−x Cl x; they were once widely used in the manufacture of carbonless copy paper, as heat transfer fluids, and as dielectric and coolant fluids for electrical equipment.
