Thermal conductivity in a substance relies on the collisions of the molecules within the substance to impart the vibrational, rotational and/or kinetic energy of one molecule to another molecule. Because the molecules in a gas are (usually) much more widely spaced than in a liquid or solid, the collisions are less frequent and it takes longer for the energy to propagate through the volume occupied by the gas. There is also the matter that because there are fewer molecules in a given volume of gas - compared to if a liquid of solid were occupying the space - there are fewer molecules impacting the heat source and the heat sink - consequently a gas is slower to pick up the heat energy from the source and transfer it to the sink. A third factor is that because gases are less dense than liquids or solids, they have a much lower heat capacity than those denser phases. The lower heat capacity acts somewhat to throttle the rate at which heat can be transferred.
Copper has a high thermal conductivity, not low. This is a good generalization of any metal, although they vary in conductivity.

conductivity is a result of free electrons meaning that they can be riped away fast and the temperature of the material. a colder material has a lower resistance and higher conductivity. materials like metallic oxides have low conductivity and materials like pure copper and aluminum have high conductivity.
skin effect. current flow concentrates near surfaces and avoids the bulk.
Argon gas has low electrical conductivity, as it is classified as a non-metal gas. However, it has good thermal conductivity, which means it efficiently transfers heat.
No, metals have high conductivity but has low resistivity.
its a high flammibillity and low conductivity
The electrical conductivity is not known. The thermal conductivity is 0.00565 W/(m·K)
Helium is typically used in making a volume gas thermometer due to its low boiling point, inertness, and the fact that it remains a gas at very low temperatures. Additionally, helium has a very low thermal conductivity, which helps in isolating the gas in the thermometer from its surroundings.
Copper has a high thermal conductivity, not low. This is a good generalization of any metal, although they vary in conductivity.
The electrical conductivity of argon is very low, somewhere around 1x10^-6 S/m under normal conditions. The thermal conductivity of argon is 0,01772 W/(m · K) (at 300 K).
Argon has a low electrical resistivity. It is a noble gas with very few free electrons available to carry an electric current, resulting in poor conductivity.
No, krypton is not a good thermal conductor. It is a noble gas and has very low thermal conductivity compared to other materials.
Argon is a noble gas and does not readily form ions or carry electric charge like metals or ions do. It has high electrical resistance and low electrical conductivity because it lacks free electrons that can move and carry electric current.
Low conductivity of water is generally better as it indicates fewer dissolved ions or impurities in the water. High conductivity can be a sign of contamination or high mineral content, which may not be suitable for certain applications like electronics or drinking water.
The electrical conductivity of gas can vary based on factors such as temperature, pressure, and the presence of impurities. Generally, higher temperatures and pressures can increase conductivity, while impurities can either increase or decrease conductivity depending on their nature.
