What are three ways to slow down the transfer of heat into an insulated cooler?

Things like wool, ice, and aluminum can keep things cooler.

Explanation:

I didn't really know if you meant an insulator or an actual cooler, but those three things stay super cold, and if you have those, it makes heat harder to get in, and stays cold for longer. I hope that helps, but yeah!

Have a good day :)

i think that d. wind is the answer.   i missed the question when i answered a. currents.
