What exactly are sparks?

Question

Are sparks electricity or fire? Or are there two different kinds of sparks?

Answer 1

There are two different kinds of sparks. They can be ignited or fiery particles thrown off by burning material such as wood,or the light

produced by a discontinuous discharge of electricity.

Answer 2

Wow, what sparked this question?

Answer 3

sparks are little fire

Answer 4

There are (at least) two different kinds of physical spark.

Electrical sparks are plasma (superheated ionized gas) created by resistive heating as current flows through gas. The hot plasma gives off light and rapidly expands creating sharp sounds.

The other kind of spark, such as that given off by a cracking fire or by a piece of metal on a grinding wheel, is glowing (and possibly burning) hot debris pulled into the air by convection, thrown into the air by abrasion, or made airborne by some other mechanical means.

Both of these can, of course, vary in intensity. A static discharge to a doorknob or a spark from a sparkler may barely be felt on the skin. At the other end, lighting or the debris from a burning building can kill and maim.

Answer 5

elec

nd theres also opposite s*x sparks too so yeah

hope this helps.

Answer 6

Yes, a spark could be an electrical discharge or a small particle of glowing matter.

Answer 7

An electric spark, usually with a flash and a sharp noise, is a momentary electrostatic discharge.

A spark is triggered when the electric field strength exceeds approximately 10 – 30 kV/cm[citation needed] (the dielectric field strength of air). This may cause a very rapid increase in the number of free electrons and ions in the air, temporarily causing the air to abruptly become an electrical conductor in a process called dielectric breakdown.

Answer 8

yes there are two kinds of sparks. An electrical spark is where there is a gap that the electricity must jump. The gap where the electricity jumps across can be seen as a bright white lightning which is call an electrical arc. This is pure electricity not fire although it can start fires like in car engines as spark plugs do.

Fire sparks are cause by heated up friction material that are release from striking two items together at a high rate of speed which when collides heats up the tiny particules that are striked together. That friction causes heat that turns bright red and is what causes sparks or sparks to fly and start fires.
