To me it looks more like a sensible approximation derived from single atoms or molecules, which might then carry over to certain kinds of ensembles under some conditions. But this latter step is not often made explicit---people actually do talk about μs of single atoms and molecules, and...
The equation is based on two effects, which are the molecular size and attractive force between the molecules. The model (43) is a modified version of the ideal gas equation V = R T / n P , where n shows the number of moles, R stands for the universal gas constant (0.0820578), T...
The term involving the parameter a corrects the pressure for intermolecular attractive forces, while the term involving b is a correction for that portion of the volume of gas that is not compressible due to the intrinsic volume of the gas molecules. We have to find the solution of a ...
The disease causes certain immune signaling molecules, called cytokines, to go into overdrive. It’s like they’re calling in fighter jets for all-out attacks on home territory. Fajgenbaum’s doctors knew his body was in a civil war, but they had questions about how and why. Fajgenbaum'...
Assuming that serpentinization only produces CH4 (not H2), an upper bound of 1 × 1011 moles of CH4 or 4 × 108 molecules/cm2/s are produced on the Earth according to the above equation. However, if rocks are ultra-mafic, serpentinization rates can be quite high in localized regions, ~...
