Thermal insulators or insulation. Or perhaps "cosy".
Yes, but not very well. All substances can conduct heat, but some are better than others.
metals and air mainly
it will heat up more more
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.
All substances can conduct heat, but nonmetals like sulfur are very poor conductors.
thermal conductivity The term for how substances conduct thermal energy is thermal conductivity.
The term used to describe how well various substances conduct thermal energy is thermal conductivity. It measures the ability of a material to transfer heat. Materials with high thermal conductivity transfer heat well, while those with low thermal conductivity resist heat transfer.
Metals such as aluminum, copper, and silver are excellent conductors of heat. Additionally, substances like water and carbon steel also conduct heat well. Materials with high thermal conductivity allow heat to flow through them quickly and efficiently.
I cannot see the list of substances in which you are referring to.
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.
