Discussion Overview

The discussion centers around the phenomenon of corona discharge, specifically focusing on the temperature of air during such an event and whether the process can be considered adiabatic. The scope includes theoretical aspects and conceptual clarifications related to electrical discharges in the atmosphere.

Discussion Character

  • Exploratory, Conceptual clarification

Main Points Raised

  • Some participants express uncertainty about the mechanisms of lightning and charge separation, noting that there is no universally accepted explanation.
  • One participant inquires about the temperature of air during a corona discharge and whether this process can be classified as adiabatic, suggesting a need for clarification on these points.

Areas of Agreement / Disagreement

Participants generally agree that the mechanisms of electrical discharges like lightning are not fully understood, but the specific questions regarding the temperature of air during corona discharge and its classification as an adiabatic process remain unresolved.

Contextual Notes

The discussion does not provide specific numerical values or definitions related to temperature or adiabatic processes, leaving these aspects open to interpretation and further exploration.

How does lightning occur ?
Please give a brief answer:smile:
Thanks in advance :smile:

We're not sure. We know that areas having a high electric potential as compared to the ground evolve under the right conditions. Eventually the potential is high enough for a discharge to occur [I think about 30KV per meter], but the mechanism of charge separaton is not understood - at least there is no explanation that is universally accepted as being definitive.
 


Okay, My question is related to this topic so I will ask it here rather than creating a new topic.

I want to know the temperature attained by the air around a
space(at normal temperature and pressure) where a corona discharge takes place.
Also can the process of corona discharge be taken as an adiabatic process?

Thanks in advance for the replies.
