metals and air mainly
Yes, but not very well. All substances can conduct heat, but some are better than others.
They are called good thermal conductors.
The substances that don't conduct heat through them are called as 'insulators of heat'. Eg - Plastic, Wood etc.
All substances, including oxygen, conduct heat. Oxygen, though, is a poor conductor of heat. Since it is a gas at room temperature it will transfer heat primarily by convection.
Thermal insulators or insulation. Or perhaps "cosy".
All substances can conduct heat, but nonmetals like sulfur are very poor conductors.
No. The ability to conduct heat (known as thermal conductivty) is a unique property of a substance. Metals, for instance, typically conduct heat better than nonmetals. But diamond is the best thermal conductor of all. The ability to absorb heat (known as specific heat) is likewise unique for different substances.
no, metal is the best heat && energy conductor.
nonmetals
Electricity does not conduct heat. Your question is meaningless.
Copper is the best conductor of heat among the substances listed. It has high thermal conductivity, allowing heat to transfer quickly through it.
thermal conductivity The term for how substances conduct thermal energy is thermal conductivity.
