Question

what effect would replacing insulation in a house with a different material that doesnt trap air?
select an answer
the temperature inside the house would decrease.
it would trap more heat inside the home.
it would conduct heat much worse.
it would be a better insulator.

Explanation:

Insulation works by trapping air, which is a poor conductor of heat. If the new material doesn't trap air, it would conduct heat more easily (opposite of being a good insulator). So it would conduct heat much worse (in terms of being a bad insulator).

Answer:

It would conduct heat much worse.
