wêrom is aluminiumfolie in goede waarmte-isolator

Aluminiumfolie is in goede waarmte-isolator, om't it in minne dirigint fan waarmte is. Warmte kin allinnich oerdroegen wurde troch in materiaal troch conduction, konveksje, of strieling. Yn it gefal fan aluminiumfolie, waarmte oerdracht komt foaral troch strieling, dat is de útstjit fan elektromagnetyske weagen út it oerflak fan in foarwerp.

Aluminiumfolie is in glâns, reflective material that reflects radiant heat back towards its source. This means that if you wrap an object in aluminum foil, it will reflect the heat from the object back towards the object, rather than allowing it to escape into the surrounding environment. This can help to keep the object warm or cool, depending on its temperature and the surrounding conditions.

Additionally, aluminum foil is a thin material, which means that it does not have much mass to absorb and transfer heat. This makes it less effective as a conductor of heat, and therefore a better insulator.

Overall, aluminum foil’s combination of reflectivity and low thermal mass make it an effective heat insulator.
