Answer 2

Insulate

Step-by-step explanation:

Air is a good insulator.

Insulators are the materials which do not allow the heat to pass through them. Some examples of insulators are plastic, rubber, styrofoam, air, etc.

Air is trapped between the two layers of glass. Here air works as an insulator and do not allow to pass the hotness or coldness through them, die to which the temperature inside the plane remains constant.
