Problem

A closed Petri dish with a radius of

2.0\,\mathrm{cm}

containing

6.0\,\mathrm{ml}

of ethanol is placed into a high-vacuum chamber with a volume of

30\,\mathrm{l}

. The dish is then opened, exposing the surface of the ethanol. How much will the ethanol level drop after a long period, and how will the height of the ethanol change over time? The temperature of the chamber and ethanol is

20\,\mathrm{^\circ\mskip-2mu\mathup{C}}
