In a chemical process, the molecules rearrange themselves. Energy is either released or absorbed. The process in a fire is called oxidation, where oxygen atoms combine with hydrogen and carbon to form waterand carbon dioxide. Oxidation is the same chemical process that turns iron into rust.

How are hydrogen molecules different to the water molecules?
One big difference: Hydrogen are an extremely explosive gas molecules (H2), while water is a fire extinguishing fluid (H2O).
Why does water get sucked by fire?
When fire burns, it creates heat which causes the water molecules to evaporate and turn into steam. This steam rises rapidly due to the heat, creating a vacuum effect that sucks in more surrounding water to replace what has evaporated. This process is known as the 'steam explosion effect'.
Why does ice still melt in water?
Fire is pure energy being released. And it takes energy to move molecules around. Where ice is concerned, the water molecule has been sapped of all energy which causes it to remain in place and stick to other water molecules.. When the energy from fire comes in contact with the water molecule, the molecule absorbs the energy which causes the molecules to break away from each other and move. When the molecules break away and move is what causes a solid like ice to become a liquid.
How does cornstarch chemically react to fire?
Fire isn't a substance or an element, (despite what RPGs and Alchemists may have led you to believe) so it technically can't react. But if cornstarch was set on fire, it would probably follow a standard combustion reaction: (hydrocarbon) + O2 -> H2O + CO2.
Why is carbon doixide a liqiud at room temperature when it is in a fire extunisher?
Carbon dioxide is a liquid in a fire extinguisher because it is kept under high pressure inside the extinguisher. This high pressure compresses the gas molecules together, causing them to condense into a liquid form at room temperature. When the fire extinguisher is activated, the liquid carbon dioxide is released as a gas, which helps smother the fire by displacing oxygen around it.
What removes air out a room during a fire?
the reaction that makes fire is fueled by oxygen therefore as the fire burns the oxygen molecules are consumed
How are hydrogen molecules different to the water molecules?
One big difference: Hydrogen are an extremely explosive gas molecules (H2), while water is a fire extinguishing fluid (H2O).
What makes crackle noise in wood fire?
The water molecules evaporating in the wood.
What happens to the molecules of fire when you put the fire out?
Fire it self is just light, heat, and sound energy produced when you burn a flamable material (Combine it with oxegen), there is no such thing as a "fire molecule". When you put out a fire all you do is remove the energy, oxygen, or fuel that is required to sustain the chemical reaction. Basicaly, nothing happens to the 'fire molecules' because they don't exist in the first place, fire is just energy from a chemical reaction. When you put out a fire you are just stoping the reaction that makes this energy.
Why is the air above a fire blurry?
The blurriness above a fire is caused by heat distortion, which is a result of the air molecules being rapidly heated and expanding. This distortion affects how light travels through the air, creating the blurry effect that we see above a fire.
How does conduction transport heat through a steel rod that is placed in fire?
In conduction, heat is transferred through direct contact between the molecules in the steel rod. When the rod is placed in a fire, the high temperature of the fire causes the molecules at the end of the rod to vibrate rapidly, transferring this energy to neighboring molecules along the rod. This transfer of energy continues down the length of the rod until the entire rod reaches a uniform temperature.
What is convection heating from a campfire?
The simplest answer is: the fire adds heat energy to the air molecules near it. The higher energy molecules start bouncing around faster. When these molecules move away from the fire, they carry the energy (heat) with them.
Does fire burn everything?
Anything that can be oxidized will burn. If the fire is hot enough it will ionize atoms and molecules then EVERYTHING will be affected even stuff that usually does not "burn" (oxidize).
What type of fire is on the Sun?
There wouldn't be fire on the sun. Fire is a chemical reaction of fuel combining with an oxidizer into new molecules. However, the sun is all plasma - no molecules at all. It's too hot for fire. The Sun is almost entirely made of plasma (i.e., over 99%) both by mass and by volume. On earth, we encounter plasma in lightning, and also in a few other situations where temperatures are extremely high.
Is water required for the movement of water molecules?
No, it requires fire. Come on, obviously you need water to do anything involving water.
A toy boat is floating in a large metal bucket If you build a fire under the bucket how the heat will transfer from the fire to the boat?
Water molecules will transfer heat as they move from the lower part of the bucket to the boat.
Does fire create energy?
Yes, fire is a chemical reaction that releases energy in the form of heat and light. The process of combustion releases energy by breaking down fuel molecules and releasing their stored energy.
