Bitesize conductors
WebInsulating materials are bad conductors and so this reduces the heat loss by conduction. The material also prevents air circulating inside the cavity, therefore reducing heat loss by convection. WebThe structure and bonding of metals explains their properties: They are electrical conductors because their delocalised electrons carry electrical charge through the metal. They are good...
