volatilization at 5 and 27 C for 30 and 7 days, respectively: R denotes remaining kerosene (% of

volatilization having a negligible effect on the density and surface tension of the
kerosene.
Once reaching the subsurface, kerosene is subject to chemical and physical
changes by volatilization, and the rate and the extent of this process controlled by
the properties of the porous medium and the ambient temperature. Different vol-
atilization through the subsurface leads to changes in the residual kerosene con-
centration. Figure
