yes it will catch fire if air is too hot.
yes depending on the moister content in the wood.in alive wood the air temp would have to be over 700 degrees celsius.but the drier the wood the less the temp needed
No, hailstones do not catch on fire when falling. Hail is formed when strong updrafts in thunderstorms cause raindrops to freeze in the cold upper atmosphere. The friction and heat generated by hailstones falling through air resistance are not enough to ignite the hailstone.
When lightning strikes grass, the electrical current from the lightning can cause the grass to catch fire. The intense heat can lead to a fire starting at the point of contact with the grass and potentially spreading to surrounding vegetation if not extinguished quickly. Additionally, the rapid expansion of air around the strike can also cause damage to the roots and surrounding soil of the grass.
No, oxygen itself does not burn, but it supports combustion. This means that it helps other materials burn when it is present in sufficient amounts. Oxygen enables fires to ignite and sustain themselves by providing the necessary conditions for combustion. If there is sufficient fuel and an ignition source, oxygen can cause a fire to burn more fiercely.
No, americium itself is not combustible. It is a radioactive metal and cannot catch fire on its own. However, it can react with air and water to form compounds that may potentially be flammable.
yes, if the wood is dry and the air is hot enough

basically a special kind of wood that won't cause the ashes to stick to the chimney, so the house catch fire Added: Fire needs three things: fuel, oxygen (air) and in most cases also a higher temperature to start.
It's technically possible, if a bit unlikely. Pellet stoves burn extremely hot, and the heated air would tend to dry out wood placed near them, making the wood more prone to catching fire.
Since air is not inherently flammable, there is no speed at which a helicopter blade would catch the air on fire.
Sulphur
Starting a fire efficiently not only requires split wood for kindling, but also dry tinder which will catch fire quickly. Once tinder has been collected and has lit, arrange the small pieces of kindling wood over the tinder, allowing enough space for air to get to the fire. If the tinder is smothered, the kindling will not catch. Continue adding small pieces of kindling, and gradually add larger pieces of wood.
When sodium and potassium are exposed to air, they react with the moisture in the air to form oxide compounds. This reaction generates heat, which can ignite the metal and cause it to catch fire. To prevent this, sodium and potassium are usually stored under mineral oil or kerosene to protect them from moisture in the air.
In air, the oxygen concentration is lower, leading to slower combustion of the wood splint. When placed in pure oxygen, the high concentration of oxygen accelerates the combustion reaction, causing the wood splint to quickly catch fire and burst into flames.
Phosphorus (especially white phosphorus) is a nonmetal that can spontaneously catch fire (VERY reactively) in air.
Candles cause fire
Wood catches on fire when it reaches its ignition temperature, typically around 300°C (570°F), causing the wood to release flammable gases. These gases mix with oxygen in the air, creating a combustible mixture that ignites. Once ignited, the wood continues to burn as long as there is a continuous supply of oxygen, heat, and fuel.
