How do fires start?
Fires start only in the presence of oxygen, fuel, and energy. There has to be enough energy provided, by either chemical, electrical, or physical means for the fuel to reach it's heat of combustion. For example, rubbing two sticks together generates heat energy by friction. If this heat energy is provided at such a rate that the fuel, wood, reaches it's heat of combustion then the wood will ignite, assuming the presence of oxygen. The reason you have to rub vigorously for wood is because the heat is dissipated in time so the energy is no longer localized.
Will 3 AA batteries ignite hairspray?
Three size AA batteries sitting side-by-side in a shelf cannot ignite a thrust of hairspray blown onto them. They have to be connected in such a way and with such a setup as to get them to either provide the spark or the heat needed to ignite hairspray. One off-the-shelf AA battery has the energy needed, through the proper arrangement, to ignite hairspray.
What is a Kelvin-Helmholtz contraction?
Kelvin-Helmholtz contraction is a contraction of a star once it is formed and before it is hot enough to ignite its hydrogen. The contraction converts gravitational potential energy into heat, some of which is radiated, with the remainder used to raise the internal temperature of the star.
What chemical property is shown when hydrogen maeks a slpint ignite?
I think you mean oxygen. However, hydrogen itself might ignite if heated enough by the splint. The chemical property is, anyway, either carbon or hydrogen's affinity with oxygen.
Could you ignite Neptune and create a small sun?
No. Neptune is not nearly massive enough to sustain any sort of nuclear reaction akin to the Sun. It simply does not have enough mass.
Can a diesel engine catch on fire if its leaking fuel?
Yes it can if the fuel gets hot enough to ignite as in leaking on a header.
What kind of energy does an unlit match have?
Potential energy, released when the match is struck.
Why doesn't paper burn when in contact with metal?
The metal absorbs the thermal energy before it can build up in the paper enough to ignite. The paper will eventually burn when the metal itself absorbs enough energy to ignite the paper.
What form of energy is a scout rubbing sticks together to start a fire?
Mechanical energy is being converted to thermal energy as the scout rubs the sticks together, creating friction that generates heat to ignite the fire.
What temperature does jet fuel ignite?
It is enough for a spark to ignite any fuel.
What would cause fluid to leak into the spark plugs of a 4 cylinder 2002 Nissan Altima?
If it is coolant that is leaking, it may be due to a blown head gasket or warped/cracked cylinder head. If it is fuel that is leaking, the spark plug or wires are faulty and there is not enough spark to fully ignite the fuel. If it is oil that's leaking, the valve seals or piston rings may be worn.
Why is my cylinder filling with gasoline?
The fuel injector on that cylinder is probably leaking and if so, there is be more fuel than the spark can ignite.

What do you mix cornstarch with to get it to ignite?
Sawdust will work if you use enough.
What is the temperature needed to ignite carpet?
hot enough to burn it
What is the lowest temperature gasoline can ignite?
Typically the lowest temperature that gasoline will produce enough vapors to ignite at is -40 degrees Fahrenheit.
Why can't a planet be a star?
A planet does not have enough mass to ignite nuclear fusion.
