How does aluminum foil keep things cooler?
Aluminumm foil paper keeps many things warm. It keeps things warm because instead of absorbing the heat that wants to get into the material you wrapped foil paper on, the foil paper refelcts back so that the heat does not absorb into the object or material.
How does reflectivity of the aluminium foil influence to keep the food warm?
Heat can be transferred by 3 mechanisms: conduction, convection, and radiation. When food is covered by aluminum foil, the foil does reduce convection a bit because the air next to the food is trapped there. A bigger effect is the reflection of the heat by the foil. Rather than continuing on its path to dissipate into the surroundings, the heat is reflected by the foil back into the food, thus helping to keep it warm.
How do things stay warm?
Things stay warm by preventing the thing it's keeping warm from losing heat. Some things that keep things warm are wool, tin foil, wood, glass, plastic, and rubber. Things that keep other things warm or cool are called insulators.
