They tested whether "incubating" a problem allowed a flash of insight, and found it did, especially when people entered a phase of sleep known as REM.

The liquid in the pipeline under certain conditions and partially vaporizes into gas state, bubble, formation of gas-liquid two-phase flow which is the process of flash.

From the experimental results, the phase diagrams, which correlate the temperature, pressure and percentage of vaporization of equilibrium flash vaporization of shale oil, are constructed.
