Because the heat {temperature} increases
You never use water to put out a fat fire, because the pouring water on burning grease or oil will not extinguish the fire. It will only cause the burning oil to splash, spreading the grease fire around.
water is not sucked in by fire. fire is like a magnet to water but they do not connect. when water is added to fire some of the water evaporates or / and weaken the fire
Fire needs oxygen to continue burning. Water cuts of the supply of oxygen and hence the fire stops.
The burning wood needs heat and oxygen as fuel. When burning wood has heat it has energy and water can quickly deprive the wood of its energy. When water comes in contact with the burning wood it takes the heat and the water turns into water vapor, a gas. The gas rises, and therefore, the heat is quickly taken from the burning wood. This is all due to water having a low boiling point. Imagine pouring water on the burning wood. Steam and smoke is produced, which is the water taking the heat into the sky, extinguishing the fire.
We do not throw water on a pan fire because of oil and water do not mix together. Oil will float on the surface of water and will leave the pan before the water. The fire is not burning the water. It's using the oil for combustion.
Burning is harmful because : 1-If the fire gets out of control, it can harm us and our homes. 2-Carbondioxide comes out of the fire which is harmful for our health and our environment. Anonymous
A fire needs oxygen to continue to burn so throwing a thick cover such as a blanket made from very thick cotton would cut off the oxygen supply, actually more effective and less messy for small fires than water is.
Fire needs Oxygen gas to burn. The water pushes the Oxygen gas away from the fire, preventing it from burning.
Fire needs oxygen to burn. If you take away the oxygen there is nothing feeding the fire so it cannot carry on burning. Water has too little oxygen in it to feed the fire, and so it snuffs the flame, putting it out.
The fire is extinguished and some of the water is evaporated. Whatever new compounds may form depends on what is burning.
