Answer» ny surface reflect back the heat to FOOD stuff wrapped in itExplanation:Aluminum is a metal which have malleable property so can be CONVERTED into thin sheets, ALUMINIUM is also a good conductor of heat but aluminum foil is used to wrap the food stuff and also kept at high temperature quite long because its shiny surface reflect back all the absorbed by the food to food itself and not conduct heat through the atmospherealuminum foil is also CHEMICALLY less reactive to the food so can be used without any harmTo know more about CONDUCTIVITY, visit:Thermal conductivity of aluminium with temperature brainly.in/question/10112301 |
