  1. Why is lightning considered a plasma? - Physics Stack Exchange

    Plasma is when the electrons are "freed" from their host atoms for a short time, due to high temperatures. Fire is plasma, it responds to electric fields. Lightning is also plasma. When a column …

  2. Why does lightning emit light? - Physics Stack Exchange

    Jul 18, 2013 · The core temperature of the plasma during the stroke may exceed $50~000\text { K}$, causing it to brilliantly radiate with a blue-white color. Once the electrical current stops flowing, the …

  3. How does the Extreme Heat of a Lightning Bolt not Kill Anyone?

    Oct 19, 2021 · This is in part because most are not "hit" directly by the main lightning bolt. Multiple 'leaders' can form between ground and main bolt, some with currents below the threshold of making …

  4. Where on Earth can you find plasma? - Physics Stack Exchange

    Lightning, Arcing (Between electrodes or in high voltage power line), The every CFL lamp that you see around, Plasma TV, Halogen Lightning. Aurora, and I am sure i am missing few others.

  5. heat - Is fire plasma? - Physics Stack Exchange

    Is Fire a Plasma? If not, what is it then? If yes why, don't we teach kids this basic example? UPDATE: I probably meant a regular commonplace fire of the usual temperature. That should simplify the

  6. plasma physics - Does Fire Conduct Electricity? Why? - Physics Stack ...

    Nov 26, 2012 · 3 Fire is a plasma and plasmas conduct electricity. This is because in a plasma an important portion of the atoms are ions. This means that there are free charges on the plasma that …

  7. Does lightning have mass? - Physics Stack Exchange

    Apr 19, 2015 · Lightning is not 'just light', it is according to this NOAA National Severe Storms Laboratory FAQ, Lightning, as best we understand, is a channel of electrical charge, called a …

  8. How is a plasma different from a metal or an ionized gas?

    Jul 7, 2022 · 17 I've just started looking at plasmas and I have some confusion. A metal is a lattice of positive ions bathed in a sea of delocalised electrons and conducts electricity. A plasma is a 'gas' of …

  9. Lightning plasma density - Physics Stack Exchange

    Jun 9, 2017 · According to [1], the plasma produced by lightning has a temperature ~ 28,000 K, and an electron density ~ 1024/m3 10 24 / m 3. What is the density of the plasma in kg/m3 k g / m 3?

  10. Could ball lightening be a form of plasma? - Physics Stack Exchange

    Apr 26, 2017 · From my reading not all descriptions of "ball lightning" could be plasma. Plasma can't last for minutes hovering and/or passing through solid objects. A free standing ball of plasma for a few …
