Aluminum foil can act as an energy barrier, but not a very good one. It is not very dense, therefore an electron (energy) can penetrate it. Because it is not very dense the molecules are not very close together it is not very good at passing energy along, which makes it a poor conductor, but it still can pass energy so it is not effective at preventing energy transfer.

How does wrapping chocolate with aluminum foil provide a barrier for light to the chocolate to increase it's life span?
the alunminium foil provides a barrier for light .
How Does aluminum foil prevent energy loss by radiation?
Aluminum foil is a conductor of heat energy. However, it does reflect radiation from heat sources, so it can reduce heat transfer through radiation. When aluminum foil is wrapped around something, pockets of air can be trapped. Trapped air is an excellent insulator against conduction and convection. However, if you want to prevent something like a can of soda from getting warm in your lunchbox, a wool sock will be a better insulator. Even paper toweling is better at insulating than aluminum foil when light is not shining.
Is a aluminum foil a compound or elements?
Aluminum is element. Aluminum foil is made entirely of aluminum.
Is cotton a better insulator than aluminium foil and tissue paper?
No, cotton is not a better insulator than aluminum foil and tissue paper. Aluminum foil is a good insulator as it reflects heat, while tissue paper acts as a thermal barrier. Cotton, on the other hand, is not as effective of an insulator because it does not have the same reflective or thermal barrier properties.
Is aluminum foil an element?
Aluminum foil is made of Aluminum, which is an element. So yes Aluminum foil is a element
What elements is used in cookwear and cooking foil?
Tin foil... tin Aluminum foil... aluminum :)
Why do the pieces of aluminum foil have different masses?
Because all aluminum foil is not equal. Aluminum foil is available in a variety of thicknesses.
Why is aluminum a pure substance?
Only a single component makes up aluminum foil, which is the aluminum element. Hence, aluminum foil is considered as a pure substance.
Which would melt first aluminum or iron?
The rate at which water freezes depends on the thermal conductivity of the container. Plastic is generally not very thermally conductive, whereas aluminum foil is more thermally conductive. Thus, as long as the foil is not very much thinner than the plastic, the water will freeze faster in the foil.
Is aluminum foil a mixture or compound?
it is an element
Is aluminum foil iron?
Shut up....iron is an aluminum foil
Is tin foil a good insulator?
What we usually refer to as tin foil is almost always aluminum foil. Aluminum is a very good conductor of heat, and aluminum foil makes a very poor insulator. The exception might be in the case of radiant energy, which it reflects well, and even better when it is polished.
