Consider a cylindrical container partially filled with ethanol (C2H6O). Using the model in which ethanol vapor pressure is a result of equilibrium between the rate of ethanol evaporation and condensation, outline step by step what happens when suddenly a piston enclosing the cylindrical container is moved down decreasing the volume of the container.
