RafaWhen a log burns in a fire, the heat causes the cellulose, hemicellulose, and lignin in the wood to break down and release gases. These gases then ignite and produce flames, while the remaining charred wood continues to burn and break down into ash. The process releases heat and light energy.

What happens to the matter in a log when it burns in a fireplace?
When a log burns in a fireplace, the matter in the log undergoes a chemical reaction called combustion. The heat from the fire breaks down the chemical bonds in the wood, releasing energy in the form of heat and light. The carbon in the wood combines with oxygen in the air to form carbon dioxide and other byproducts like water vapor and ash.
What happens when fire reacts with pure oxygen?
When fire reacts with pure oxygen, it undergoes rapid combustion and burns more vigorously. This reaction releases more heat and light compared to when fire reacts with normal air. It can result in a more intense and hotter fire, which is why oxygen tanks are dangerous in fire emergencies.
4. A log is reacting with oxygen as it burns in a fireplace. If the amount of oxygen reaching the log is reduced what happens to the rate of this chemical reaction?
If the amount of oxygen reaching the log is reduced, the rate of the chemical reaction (combustion) will slow down. This is because oxygen is a reactant in the combustion process and reducing its availability will hinder the reaction from proceeding at the same rate.
When wood burns in fire what happens to the wood?
When wood burns in a fire, it undergoes a chemical reaction called combustion where the wood reacts with oxygen to produce heat, light, and various byproducts such as carbon dioxide and ash. The cellulose and lignin in the wood break down and release energy in the form of heat, leading to the characteristic flames and embers in a fire.
How much does a log for the fire weigh?
The weight of a log for a fire can vary depending on the type of wood and its size. On average, a medium-sized log can weigh around 10-20 pounds.
