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

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!!

∙ 13y agoAluminum, 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.

∙ 12y agobecause it acts as an heating element to reheat the food and the heat source for the heating precess comes from the food itself.

Can thermal energy flow from cooler objects to warmer objects?
energy alwayy flow from high density to low density
Is aluminum good for keeping drinks warm?
aluminum is a netrual substance it doesnt make liquid any warmer or colder
When two objects are in direct contact the heat is transfered by?
Heat will be transferred by conduction from the warmer surface to the colder one.
Are temperatures further from the equator hotter or colder?
The temperatures are warmer closer to the equator.
How does the movement of molecules in warm objects compare with the movement of molecules in cooler objects?
warmer molecules are more excited and therefore move faster than colder molecules
What do the colors mean on a thermal camera?
The lighter or redder the color appears, the warmer the object is. This is how you can determine what objects are people or animals on a thermal camera. Nonliving objects, or colder objects, will appear blue or purple on the camera.
Heat flows from what temperature to what temperature?
High temperature always flows to low temperature, never the other way around.
Do starfish prefer warmer or colder waters?

If a cold front passes over you does it get warmer or colder?
colder
Is the Arctic circle colder or warmer than Antarctica?
Warmer
What happens if two objects with a different temperature touch?
the heat from the warmer object will move to the colder object, for heat can only move in one direction.
