Why does food wrapped in aluminum foil keep warm for a long time?

• Aluminum foil is an insulator and prevents heat loss by conduction.
• Aluminum foil forms an air-tight seal and prevents heat loss by convection.
• The silver surface of the foil reflects heat in and prevents heat loss by radiation.
• The silver surface of the foil absorbs heat from the surroundings and keeps the food warm.
