Fire is some kind of fuel burning in oxygen. If you blow gently on a fire more oxygen will get to it and it will burn more fiercely. A fuel will not burn, even in a plentiful supply of oxygen, until it reaches ignition temperature. When a fire is alight, the already burning fuel heats the fuel near to it. When this nearby fuel reaches ignition temperature it too bursts into flame. If you blow air very fast at the fire, the burning fuel is blown away from the fire before it has had time to heat the fuel around it to ignition temperature.

Blowing air or fanning a small fire makes it stronger or bigger?
blowing air gives more oxygen so it makes the fire bigger
'why does the fan still run on the unit after it cycles is over. But it is blowing hot air not cold?

Why is your central air condition blowing warm air?
there are 3 main reasons that your a/c is blowing warm during a call for cooling they are 1.the electric resistance heater is on 2. the reversing valve is energized in a Heat Pump, or you are low on refrigerant
Why is your refrigerator blowing warm air?
Your compressor is not working. Through evaporation compressors cool the evaporator coil and the fan blows air across it. So if the fan is blowing hot air the compressor is not cooling the coil. But check to see if the dial inside the fridge is turned to "more cold" , that turns the compressor on.
Why is furnace blowing cold air?
If it's blowing intake-temperature air, either you've got the fan alone switched on or the heating part isn't working for some reason. If it's a gas furnace, the pilot light may have gone out, or the gas may be shut off somewhere (at the furnace itself, at the emergency shutoff for the house, or possibly at the main inlet). If it's blowing actually COLD air (colder than intake), then you've probably got central air and you've somehow managed to turn on the air conditioner.

Why fire increases on blowing exhaled air to coal chulla or bhatti while candle extinguish on blowing exhaled air?
When blowing on a fire it increase air flow. This in turn provides more oxygen which fires need to sustain themselves. In the case of candles, they are too small to handle the air flow.
Why is your home air conditioner blowing air but no cold air is coming out?
my air conditionel is blowing hot air what i need to do how i put air in my home window conditional
Why fire burns when you blow?
if you mean blowing air from your mouth into an open flame then you are adding oxygen to the fire making it bigger and/or hotter :)
Why havent i got heat coming from my electric fire its just blowing cold air?
Obviously it is broken.
Why you blow on a match it put it out?
Any extinguishment of fire is caused by removal of one or more parts of the fire tetrahedron: Oxygen, Heat, Fuel, & Chemical Reaction. In the case of blowing out a match you are removing HEAT. You are disrupting the area of heat being caused by the match and by blowing more air onto it, you are in fact displacing the heat. Sustained combustion must occur at certain temperatures depending on the fuel and level of oxygen, thus blowing air at a fast rate onto the match causes the temperature to drop below this temperature and go out.
Does the wind clean the air?
depends if it is blowing in fresh air and blowing out polluted air or vise versa
How do firefighters put out fire storms?
They really can't put them out. When a fire gets that bad it sucks out all the oxygen in the air and it will pull people into the fire.
What is the best method to put out a gasoline fire?
Smother it- cutting off the air from the fire.
Can a fire blanket put out a fire?
Yes, provided the fire is not too large and is not a chemical fire that can burn without air.
Your car not blowing air or heat what's wrong?
Car not blowing air or heat
Why do you use foam to put out a fire?
The foam cuts the connection of fire with air (oxygen) & thus puts out fire.
