Question

material selection strategy here are the meterial option 1st structure 2nd is predicted insulation quality. Here are the options cotton balls bubble wrap crumpled paper aluminum foil its like a table so for example cotton balls u have to answer it with structure and predicted insulation quality and make sure the answer is short

Answer 1

- Cotton balls — Structure: loose fibrous matrix trapping air; Predicted insulation: high
- Bubble wrap — Structure: sealed air pockets; Predicted insulation: medium-high
- Crumpled paper — Structure: irregular fibrous layers with air pockets; Predicted insulation: medium
- Aluminum foil — Structure: thin reflective metal sheet; Predicted insulation: low (effective only as a radiant barrier with an air gap)
