How does aluminum foil keep some objects warmer and colder then plastic wrap?

Answer 1

A paper towel transfers heat at a much lower rate than plastic wrap or aluminum foil. A paper towel or two wrapped completely around the item(s,) so that air is sealed fairly well, is your ticket!!

Answer 2

Aluminum, like other metals, has a higher conductivity than plastic (which is an insulator). Heat is conducted through aluminum, and if you have a lot of it (high surface area) it acts as a "sink" for the heat. If you place a hot object on a sheet of aluminum and place a fan over it, the heat from the object will be transferred into the aluminum and then convected (transferred via the air) away.

Answer 3

aluminum foil keeps food colder because its molecules are more dense, plastic wrap are less dense

Answer 4

because plastic wrap has a zipper in which when u put food in it , it keeps the food's energy in back to the food

Answer 5

because it acts as an heating element to reheat the food and the heat source for the heating precess comes from the food itself.
