Aluminium foil minangka insulator panas sing apik amarga minangka konduktor panas sing ora apik. Kalor mung bisa ditransfer liwat materi kanthi konduksi, konveksi, utawa radiasi. Ing kasus aluminium foil, transfer panas dumadi utamané liwat radiation, yaiku emisi gelombang elektromagnetik saka permukaan obyek.
Aluminium foil iku mengkilat, 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.
Kajaba iku, 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.
Sakabèhé, aluminum foil’s combination of reflectivity and low thermal mass make it an effective heat insulator.
