Heat moves easily through materials with delocalised electrons, that is electrons which are free to move through the substance. This happens in metals and graphite.
Heat flows easily on conductive materials.
Conductors.
Heat flows easily in a good thermal conductor.
Metal
Wood is a porous material in which a lot of air is trapped, and as a result, it is a poor conductor of heat. Iron is a denser material which is a good conductor of heat. So when you touch iron, heat flows easily from your finger into the colder piece of iron. Heat flows much more slowly from your finger into a piece of wood, even if the wood is exactly the same temperature as the iron.
Plastic.
plastic
Heat flows easily in a good thermal conductor.
conductivity
It is a material through which heat can be transmitted easily.
metal
metal
Metal
the material can gain or lose heat easily
Material Like Aluminum Pans And Metal Spoons,that Easily Transfer Heat
