What happens to wood when it burns and why does it undergo such a transformation?
When wood burns, it undergoes a chemical reaction called combustion. The heat from the fire breaks down the wood's complex molecules, releasing carbon dioxide and water vapor as byproducts. This transformation occurs because the heat provides the energy needed to break the bonds holding the wood's molecules together, allowing them to rearrange into simpler compounds.
What happens when wood burns and why does it produce heat and light?
When wood burns, it undergoes a chemical reaction called combustion. During combustion, the wood reacts with oxygen in the air to produce heat and light. This process releases energy in the form of heat and light because the bonds holding the molecules in the wood together are broken, releasing stored energy. The heat and light produced during combustion are the result of this energy being released.
What happens to molecules during friction?
During friction, molecules at the contact surfaces interact with one another. The force of friction causes these molecules to resist motion, generating heat in the process. This heat is a result of the molecules vibrating and colliding with each other.
Why the wood is bad conductor of heat?
Oh, dude, so like, wood is a bad conductor of heat because it has this molecular structure that's all spread out and chill, making it hard for those heat vibes to pass through. It's like the cool kid at the party who's just too laid back to get involved in any drama, you know? So yeah, that's why wood is a bad conductor of heat, but like, who really cares, right?
What type of energy is wood?
It is the breaking of chemical bonds, and therefore is releasing chemical energy.
What happens to the molecules when wood burns?
When wood burns, the heat breaks down the complex molecules of cellulose and lignin in wood into simpler molecules. These simpler molecules release as gases like carbon dioxide and water vapor, while the remaining solid residue is primarily composed of carbon, which is what produces the ash you see after burning wood.
What happens when molecules are removed from heat?
the molecules will decrease in motion

What happens when fast moving molecules touch other molecules?
Heat transfer
What happens when wood burns and why does it produce heat and light?

This process releases energy in the form of heat and light because the bonds holding the molecules in the wood together are broken, releasing stored energy. The heat and light produced during combustion are the result of this energy being released.
Why does the sauce pan handle don't get hot?
Because wood is not a good conductor of heat. The molecules in wood are not very close to each other; therefore the heat cannot travel through the molecules and you can't feel the heat. Metal is a good conductor of heat because the molecules are very tightly packed together, so the heat can travel through easily. Hope this helps
What happens to the molecules of a substance when it is melted?
the molecules vibrate, faster and faster as the heat increases then they become disordered
What happens to atoms of A substance when heat is added?
When heat is added to a substance, the molecules and atoms vibrate faster.
What is a chemical reaction that happens in home and gives heat?
Burning wood in a fireplace is a common chemical reaction that produces heat. This involves the combustion of wood, where oxygen from the air reacts with the wood to release heat energy.
What happens to the energy of glucose that is not used to nake atp molecules?
The energy not used to make ATP molecules generates heat.
What happens to all matter when heat?
the atoms use the energy to move the molecules
What happens when molecules are heated and why?
They move faster because the heat gives them more energy
