Answer:
<em>The water will diffuse into the air.</em>
Explanation:
Diffusion can be described as a process through which molecules travel from an area of higher concentration to an area of lower concentration along the concentration gradient. Such processes do not require energy. As the concentration of water is less in the air surrounding the cell as compared to the inside of the cell hence, the water molecules will move out of the vacuole and into the air by the process of diffusion.
