Yes, but not by itself. Fire still needs a source of fuel to ignite. Air has a % of oxygen which the fire needs to feed on. Air is not conbustible but it will feed a fire get higher and bigger.
No, water itself cannot catch on fire because it is a compound made of hydrogen and oxygen. However, the hydrogen in water can catch on fire if it is separated from the oxygen and ignited.
Water itself does not catch on fire because it is a non-flammable substance. However, if there are impurities or contaminants in the water, such as certain chemicals or gases, those impurities can catch on fire and create flames on the surface of the water.
No, it is not possible to catch a bullet with your bare hands due to its high speed and force.
There are a number of elements which will burn in air (if they are ignited) but which will not burn under water. An example is carbon. Coal, which is made mostly of carbon, burns in air but not under water.

Since air is not inherently flammable, there is no speed at which a helicopter blade would catch the air on fire.
Sulphur
Hot dry air alone is unlikely to cause wood to catch fire. However, if the temperature is high enough and there is an ignition source present, such as a spark or flame, the hot dry air can contribute to the wood catching fire more easily due to its reduced moisture content.
No its not possible for the river to catch on fire here in 2012 because the people that work for the city of garbage have stoped put there wastes in the Cuyahoga River.
yes, if the wood is dry and the air is hot enough
It is possible for aluminum pie plates to catch on fire outside in the sun if they become extremely hot or receive focused sunlight. It would be very rare for them to catch on fire.
Phosphorus (especially white phosphorus) is a nonmetal that can spontaneously catch fire (VERY reactively) in air.
No, it is not possible to make your breath so hot that it will make an object catch fire because our breath contains carbon dioxide and moisture.
because it is fat
Hidrogen explodes when ignited if it's in the presence of oxygen.
Yes, it is possible to do so.
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.
