WebConduction in good conductors (metals) is caused by collisions between fast moving free electrons and metal ions and by passing vibrations from atom to atom. Conduction by … 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.
