Is foil good for keeping something warm?

Foil itself will not warm it, it has to already be warm for it to insulate it.


What keeps things colder aluminum foil or Styrofoam?

Styrofoam is better at insulating and maintaining temperatures than aluminum foil. Styrofoam has low thermal conductivity, meaning it doesn't easily transfer heat, while aluminum foil is a good conductor of heat, allowing it to quickly reach the same temperature as its surroundings. This makes Styrofoam better at keeping things cold for longer periods of time.

What is the emissivity of aluminum foil and how does it affect its ability to reflect or absorb heat?

The emissivity of aluminum foil is low, around 0.03. This means it is a good reflector of heat and does not absorb much heat. As a result, aluminum foil is effective at reflecting heat and keeping objects cool.


What are good materials to keep things cool?
