  1. Why do we still need to know about the Rankine temperature scale?

    Jul 12, 2018 · The Rankine scale (/ˈræŋkɪn/) is an absolute scale of thermodynamic temperature named after the Glasgow University engineer and physicist William John Macquorn Rankine, who proposed …

  2. What happens to pressure when a liquid goes supercritical?

    Feb 2, 2024 · Interesting that twice the pressure means half again the velocity in firearms, and twice the temperature seems to equal about half again the efficiency in Rankine-cycle power plants.

  3. Ranking order of nucleophilicity - Chemistry Stack Exchange

    May 29, 2020 · The first thing to note is that nucleophilicity is a kinetic parameter that cannot be addressed easily with thermodynamic parameters such as electronegativity. Instead, you need to …

  4. Determining boiling point on a created temperature scale

    Nov 6, 2016 · 1.Assume that you construct a thermometer using gallium as the fluid instead of mercury, and that you define the melting point of gallium as 0 °G and the boiling point of gallium as 1000 °G. …

  5. Why is the volume of one mole of gas 22.4 or 22.7 dm3?

    Oct 2, 2024 · It will assume different units and values depending on for instance whether the pressure is expressed in units of atmosphere ($\pu {atm}$) or pascal ($\pu {Pa}$); temperature in degrees Kelvin …

  6. thermodynamics - Is the ideal gas constant not a constant if Celsius is ...

    Nov 18, 2016 · 3 If you consider temperature to be the measure of mean kinetic energy, then to get the correct linear scale, you'd need an absolute temperature. The Kelvin scale (or the Rankine scale) …

  7. evaporating DMSO/Ethanol - Chemistry Stack Exchange

    May 8, 2023 · However, you can say Celsius, Fahrenheit, or Rankine. Preferably, don't use "°" for absolute temperature scales like kelvin or Rankine, and use $^\circ F$ or $^\circ C$ for Fahrenheit …

  8. Are there any major exceptions when comparing electron affinity?

    Apr 30, 2012 · This exception rule is actually orbital filling rule. For two electrons to be in same orbital they need to have different spins (Pauli exclusion principal). This electron pairing requires additional …

  9. Fehling's Solution + Aldehyde (which is oxidised)

    Oct 28, 2024 · The copper in Fehling's solution has a +2 oxidation state, while it has a +1 oxidation state in the red precipitate, $\ce {Cu2O}$. This is the reduction half reaction. The oxidation half reaction …

  10. Making hard water - Chemistry Stack Exchange

    Apr 15, 2019 · Does anyone know how to make hard water with a hardness of 200+ ppm in terms of $\\ce{CaCO3}$? I live in Seattle and we have very soft water and we need hard water for testing …
