... 18. At very high pressures (~ 1000 atm), the measured pressure exerted by real gases is greater than that predicted by the ideal gas equation. This is mainly because A) the volume occupied by the gas molecules themselves becomes significant. B) real gases will condense to form solids at 1000 atm pre ...

Separation and Purification Methods
... The other methods fall under the category of LC (liquid chromatography), where the mobile phase is a solvent system, which can be used instead of temperature to leverage retention. Occasionally, this is a single solvent, but more often it is a binary mixture of solvents with different polarities. Th ...

... Temperature is a measurement of how hot or cold something is. It is a calculation of the average kinetic energy of all the particles in the substance. Scientists theorize that at absolute zero, or –273.15oC, particle motion stops and that no more energy can be removed from the object. So this is the ...
