✔ 最佳答案
If the substance can release VOCs, then the box containing it will not be vaccum until all VOCs are released. "Vaccum" means that there is "no" (in practice, vaccum means a very very low concentration of gas molecules present) gas molecule present. Whenever you attempt to remove the VOC from the box, it will release more VOCs until equilibrium was met.
