Answer:

Air is a poor conductor of heat.

Explanation:

Air molecules are far apart from each other, making it difficult for them to collide and transfer energy.

Example of air being a poor insulator

  • Birds trap air under their feather to keep warm
  • Styrofoam food packaging being able to keep its contents warm is due to the pockets of air in the styrofoam material
