the materials like metal(which have free electrons) conduct heat and light both and those materials which are formed by covalent bond (do not have free electrons) generaly non metals do not conduct heat and electricity.
copper, metals...
All materials conduct heat so: Yes The real question is how quickly.
Insulators do not conduct heat and are therefore non-metals. Metals do conduct heat, and vey well may i add. But, for the record, you're thinking of electricity. Potatoes conduct heat, and they're not metals. Anyone who has held a lump in their hand will tell you that playdough conducts heat, in fact, rather a lot of other materials conduct heat and water also conduct heat
Usually, yes.
The general term for "materials that conduct heat poorly" is "insulators". Examples would be wood, many ceramics, and cloth such as wool or cotton.
Any material that has free electrons.
The best conductor for heat and electricity is any type of metal element.
The ability for a metal to conduct heat depends on how the atoms are aligned. Different materials have different bond structures.
Heavy materials are important in cooking because they conduct heat much better than light material equipment. These materials are slow to heat up, however.
Ye, but this characteristic is extremely different between materials.
Materials that can conduct heat are called good conductors of heat and electricity. Most of the time, these materials are metals. Nonmetals are not good conductors of heat.
Some materials that conduct include gold, wood, steel, water, and even copper. Most metals conduct well and are used to carry heat or electricity. Aluminum is another metal that conducts well.
