The answer is below.

Work Step by Step

As the vacuum removes air, the pressure begins to drop. This lowers the vapor pressure, allowing more water to vaporize and thus decreasing the volume. However, we know that through lowering the pressure to a low enough value, water will be able to freeze since the liquid state is not possible at this temperature. The water will thus depose and sublime until an equilibrium vapor pressure is reached.
