1) One capacitor plate is positively charged and the other capacitor plate is negatively charged. Unlike charges attract, so a large charge on capacitor plates with a small air gap would tend to close that air gap due to electrostatic attraction. A dielectric material would resist this tendency much more than an air gap.
