Question

Just a question... Worth 45 points!

What one do you think will keep a cup of coco warm for the longest period of time. Give me definitions on each one in order for wamer to colder and why.
2 layers of foil around the cup
A ziploc bag with the cup in side of it
2 socks on the cup
cup alone
cup within another cup

And plz answer my question correctly :D
Thank You!!!

Answer 1

The insulator that would most likely keep the cup warmer is the two layers of foil.

Answer 2

I believe the cup within another would keep it warm the longest because it would insulate the heat within the main cup, that or you could just leave it in a microwave ^-^

Hope this sorta helps XD
