Heat conductance occurs when two atoms or molecules interact with one another. This means that they must be reasonably physically close to one another. Because the density of a gas is so much lower than that of a solid or liquid, it will not conduct heat well.
The conductance of electricity also requires a high density, but more importantly, since electricity is the flow of electrons, it requires that only minimal energy be required to excite electrons from the valence band to the conductance band. In metals, this band gap is extremely small, allowing large numbers of electrons to be excited to the conductance band by relatively little energy. Suffice it to say, no metal is a gas under any reasonable conditions.
Liquids and gases are not good conductors of electricity because their particles are not tightly packed together like in solids, so there are fewer free electrons available to carry charge. In addition, the ions in liquids and gases are not as free to move and carry charge as in solids, making them poor conductors of electricity.
Liquids and gases are poor conductors because of how their molecules are dispersed. Unlike solids that have their molecules close together, liquids and gases have theirs spread out making it nearly impossible to conduct anything.
The valence (outer) shell of the atom determines whether it's a conductor, semiconductor, or an insulator. Each shell can hold only a certain amount of electrons, once it's full, another shell is added. If a valence shell has few electrons, the electrons can easily move from one atom to the next, making it a good conductor. If it's half full, it's a good semiconductor. If it's almost full or full they cannot move easily between atoms, making it a good insulator. Non-metallic elements are poor conductors, that is why gasses are poor conductors.
It sure is possible. However, in liquids and gases, there is also convection - and that often becomes the predominant method of heat exchange.

Is a gas a good thermal heat conductor?
Yes, gases are generally poor thermal conductors compared to solids and liquids. This is because gases have low density and their particles are further apart, making it harder for heat to transfer through them by conduction. Heat transfer in gases primarily occurs through convection rather than conduction.
What property does liquids and gases share?
Liquids and gases both take the shape of their container. This is because the particles in liquids and gases are free to move past one another, allowing them to flow and conform to the shape of their container.
What are the physical properties of nonmetals?
Nonmetals are typically brittle solids, liquids, or gases at room temperature, and they are poor conductors of heat and electricity. They tend to have lower melting and boiling points compared to metals and are more likely to be dull or have a non-shiny appearance. Additionally, nonmetals are often more non-reactive and have higher electronegativity compared to metals.
What are the differences between liquids and gases?
Liquids have a definite volume and take the shape of their container, while gases have neither a definite volume nor shape, filling the entire space available to them. Gases are compressible, while liquids are not. Additionally, gases exhibit lower intermolecular forces compared to liquids.
What are two physical properties of nonmetals?
not only are there two but four:Poor conductors of heat and electricity.Brittle - if a solid.Nonductile.Do not possess metallic luster.Transparent as a thin sheet.Solids, liquids or gases at room temperature.
Why are liquids and gases not good conductors of heat?
i have no earthly idea. I'm clueless
Are solids better conductors than liquids and gases?
particle density
Which are the worse conductors of heat liquids or gases?
Gases are generally worse conductors of heat compared to liquids. This is because gases have more space between their particles, leading to less interaction and slower heat transfer. Liquids have particles that are closer together, allowing heat to be transferred more efficiently.
Are organic liquids good conductors of electricity?

Can gases and liquids carry heat by conduction?
Yes, gases and liquids can carry heat by conduction, although they are generally considered to be poor conductors compared to solids. In gases and liquids, heat is transferred through collisions between molecules and the flow of energy from higher temperature regions to lower temperature regions.
Can eletricity travel through solids and liquids and gases?
Yes, electricity can travel through solids and liquids as they contain charged particles that can conduct electricity. However, gases are poor conductors of electricity as they have fewer free-moving charged particles than solids and liquids.
What liquids that are good conductors of electricity?
water,and metal that has been melted down
Why are gases the worst conductors of all?
Gases are poor conductors of heat and electricity because their particles are widely spaced and have weak intermolecular forces. This means that heat and electrons cannot be transferred efficiently between gas particles, resulting in low conductivity. Liquids and solids, with their closer particles and stronger intermolecular forces, are better conductors than gases.
What are the differences between a metal substance and a non-metal one?
Metals are good electrical and heat conductors. They are malleable, ductile, and generally solid at room temperature. Nonmetals are poor conductors of heat and electricity. They form brittle solids and are nonductile. They are generally liquids or gases at room temperature.
Why are some liquids and some gas conductors of electricity?
molten metals are liquids that conduct electricity (mercury is molten at room temperature)electrolytes are liquids that conduct electricity (acids, salts, or bases either dissolved in water or molten)ionized gases conduct electricity (unless ionized gases are excellent insulators)
Can electric charges travel through wires?
Electric charges can travel through solids, liquids, or gases. They can travel through conductors, insulators, and semiconductors.
Is gas a good conductor of electricity?
Air and other gases are usually good insulators but sometimes they can be good conductors
