Because you are supplying more oxygen, faster.
Blowing on a fire increases the supply of oxygen, which is necessary for combustion. More oxygen allows the fire to burn more efficiently and thus increase in intensity rapidly.
Using air to blow out small fires helps remove the oxygen necessary for combustion, putting out the fire. On the other hand, blowing air into a fire can increase the oxygen supply, providing fuel for the fire to grow larger. The key difference is the control and direction of airflow in relation to the fire.
When you fan a fire or blow on it through a tube, you increase the flow of oxygen to the flames. Fire requires three elements to burn: heat, fuel, and oxygen. By enhancing the oxygen supply, you help the combustion process, allowing the fire to reach a higher temperature and reignite any unburned fuel, causing it to blaze again.
Yes. By lighting TNT with fire, (lava, flint and steel), the TNT will start to blow up.
Oxygen feeds fire, but for a candle, it is too small to withstand the pressure of a good blow, and the fire is easily blown out in the wick, where the core of the fire is. In a bigger fire though, like a campfire, it is too big for a human to blow it out, and so the oxygen feeds it, and makes it glow brighter temporarily.
When bellows are used to blow air onto a fire, they increase the oxygen supply available for combustion. More oxygen allows the fuel to burn more efficiently and at a higher temperature, resulting in a brighter flame. This process enhances the fire's intensity and can help it consume fuel more rapidly. Consequently, the increased airflow from the bellows contributes to a more vigorous and luminous fire.
Combustion or oxidation.
fire
I mean "combustion".
combustion
just blow on the screen
Blow-by is usually caused by worn piston rings that do not seal properly during the combustion stroke.
