The amount of a solid substance that dissolves in a gas or in a liquid is affected by all of the following except:
A- the nature of the substance
B- the temperature
C- the pressure
D- Stirring (Agitation)

Substance a is a nonpolar liquid and has only dispersion forces among its constituent particles. substance b is also a nonpolar liquid and has about the same magnitude of dispersion forces among its constituent particles. when substance a and b are combined, they spontaneously mix.
