Explain why at high temperature and low pressure gases conduct electricity
At high temperatures and low pressures, gases become ionized, meaning that the atoms or molecules in the gas lose or gain electrons, creating charged particles called ions. These ions are able to move freely and carry electrical charge, making the gas conductive.
When a gas is heated to high temperatures, the kinetic energy of the particles increases, causing collisions between the gas molecules or atoms. These collisions can result in electron transfer, creating positively charged ions (cations) and negatively charged ions (anions) within the gas. These ions are able to carry electric current, allowing the gas to conduct electricity.
Similarly, at low pressures, the distance between gas molecules or atoms increases, allowing for easier movement of charged particles. This can also result in ionization of the gas and the ability to conduct electricity.
Overall, at high temperatures and low pressures, the increased kinetic energy and decreased particle density allow for more efficient ionization and movement of charged particles, leading to the gas being able to conduct electricity.
