Gases are poor conductors of heat because the molecules in gases are far apart and have weak intermolecular forces. This makes it difficult for heat to be transferred between gas molecules, resulting in low thermal conductivity. Additionally, gases have low density compared to liquids and solids, which further contributes to their poor heat conductivity.
The last time I checked the worst conductor of electricity is rubber.
The best conductor of heat is silver, followed by copper and aluminum. The worst conductor of heat is typically materials like wood, paper, and plastic.
Silver is one of the best conductors of electricity due to its high electrical conductivity. In contrast, rubber is one of the worst conductors of electricity because it is an insulator and does not allow electrical current to flow easily.
The Earth's atmosphere is primarily an insulator, as it is mostly composed of gases which do not conduct electricity well. However, under specific conditions such as during a lightning strike, the atmosphere can briefly become a conductor.
a solid because particles of a solid is not as put together.
Aluminium is a good conductor of heat.
No.

it depends like there are some solids which are better conductors than others but I think that gases are the worst conductors of heat as they have lots of spaces between there molecules and so heat cant pass throught them....
The answer is dryed air (0,024 W/m.K).

Virtually every substance is a conductor of electrical current to a greater or lesser degree. We use the best ones to build extension cords and to connect electronic components to one another, and we use the worst ones as 'insulators'. Rubber is one of the worst ones.
The worst metal conductor of heat is very probable bismuth with a thermal conductivity of 7,97 W/m.K.-------------------------------------------------------------------------------------------Aluminum conducts heat brilliantly, which is why it is used for most heat sinks and cooling fins, along with copper, another brilliant conductor of heat.--------------------------------------------------------------
I believe that rubber is the worst conductor of electricity. Rubber is amorphous. The atoms within the rubber are not aligned in any particular order, so electrons do not move between them easily. In fact, rubber is used to protect against being shocked by electricity, by having wires be covered by the rubber.
