When we pass electricity through a gas , the gas molecules get excited and give out electrons and the gas molecules become positively charge (form ions).
As the ions are positively charged and the electrons are negatively charged they have a tendency to recombine and for a neutral gas molecule again.
(Note- High pressure=molecules are more close [more crowding]
Low Pressure=molecules are not so close[less crowding] )
At atmospheric pressure the gas molecules are more closer to each other that's why they recombine easily avoiding the electrons to flow.
At low pressure the gas molecules are not so close and hence it is difficult for the ion and the electron to recombine and form a neutral molecule.
This results into flow of electrons and hence the gas starts to act as an conductor.
What else can I help you with?
Are gases conductors?
Most gases are poor conductors of electricity because they do not have free-moving electrons to carry electric current. However, some gases can become conductive when ionized, meaning their atoms gain or lose electrons, creating charged particles that can carry electrical charge. Examples include ionized gases in fluorescent lights or plasma TVs.
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.
What is pressure and how does it affect the behavior of gases?
Pressure is the force exerted on a surface per unit area. In gases, pressure affects their behavior by influencing their volume, temperature, and density. When pressure increases, gases are compressed and their molecules move closer together, leading to changes in volume and temperature. Conversely, when pressure decreases, gases expand and their molecules move farther apart.
Can gases expand or contract?
Yes, gases can both expand and contract. When heated, gases expand as the molecules move more rapidly, increasing the pressure and volume. Conversely, when cooled, gases contract as the molecules slow down, decreasing the pressure and volume.
Why gases flow through pipes?
Gases flow through pipes due to differences in pressure. Gas moves from areas of high pressure to low pressure, creating a flow. This flow is essential for transporting gases for various applications such as heating, cooling, and production processes.
Are gases conductors?
Most gases are poor conductors of electricity because they do not have free-moving electrons to carry electric current. However, some gases can become conductive when ionized, meaning their atoms gain or lose electrons, creating charged particles that can carry electrical charge. Examples include ionized gases in fluorescent lights or plasma TVs.
What are the electrical properties of gases?
Gases are poor conductors of electricity in their natural state because their molecules are too far apart to facilitate electron flow. However, some gases can become conductive when ionized by high voltage or temperature, leading to their use in applications like neon lights or plasma displays. Additionally, gases can act as insulators in certain conditions, such as the insulating properties of air in electrical transmission lines.
All gases become liquids when cooled to their what point?
All gases become liquids when cooled to their respective boiling points. At this temperature, the vapor pressure of the gas matches the external pressure, causing the gas to condense into a liquid state.
Does it have to be a noble gas in neon lights?
Neon lights are usually with neon or other inert gases at a low pressure, where when voltage gets through they shine.
Poor conductors of heat and electicity?
gases and many plastic materials
What are the types of poor conductors of heat?
Gases. Especially if you keep it from circulating.
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.
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.
Experiment to prove that gases are poor thermal conductors?
There are many experiments you can perform in order to prove that gases are poor thermal conductors. You can try heating up an enclosed space from the top and feeling the bottom for example.
Why are liquids and gases not good conductors of heat?
i have no earthly idea. I'm clueless
Are non metals?
non metals are gases and are poor conductors at room temperature
