The wood changed to carbon dioxide, water vapor, and other gases that floated off into the air, leaving behind just the ashes
It changed to other gases
It changed to ashes
It changed to Carbon dioxide
It changed to water vapor
It was destroyed
More matter was created
All the matter changes to fire
What happened to the matter changed to when burning a fire?
Maybe
It evaporates into nothingness
No
No, because of conservation of mass
It just changes form
Is any matter destroyed when you burn wood in a campfire?
It changes into air and heat
It is destroyed in the air
It travels through the air
It changed changes into carbon dioxide, water vapor and other gases
Into the air (as carbon dioxide, water vapor, and other gases)
After you burn wood in your campfire, the wood matter ends up on the ground (mostly as ashes), but where does the rest of the matter go?
Assume you had also trapped the gases released by the burning wood and measured their mass and the mass of the ashes; the ashes and gases combined have the same mass as the wood you started with
The ashes and gases have the same composition
The ashes and gases combined have the same original mass
New matter is created to replace the destroyed matter
The matter takes on different forms
How is matter conserved after wood burns?
Heat
Water
Burning the wood
Cold
Law of conservation of mass
Fire
Campfire
Ashes
What can cause wood to change to ashes, carbon dioxide, water vapor, and other gases?
Matter can be created or destroyed
Maybe
No
No, because of conservation of mass
Yeah
Matter cannot be created or destroyed
Is any matter created when you burn wood in a campfire?
Example of residue left back when something is burnt
Example of fire and heat
Matter
Anti matter
Law of conservation of mass
Example of water vapor and carbon dioxide
Ashes and gases in an example of what?
Law of energy transfer
The law of conservation of mass
Law of equal and opposite reaction
The fact that ashes and gases combined have the same mass as the wood you started with illustrates what law?
They change into pile of ashes
They are permanently eliminated from the earth
As the fire burns, the stack slowly shrinks and a while later, all that is left is a small pile of ashes
They get converted to fire and heat
They are converted to ashes and gases
What happens to sticks and logs in a campfire?
The stack of sticks and logs
The ashes
Stack of ashes
The stack of sticks
As a fire burns, what stack slowly shrinks?
The wood changed not only to ashes, but also to carbon dioxide, water vapor, and other gases
Small pile of ashes
Only the ashes,All other matter was destroyed
Only the ashes, all other matter changed forms and moved away from the fire
Big pile of ashes
Ashes
Once a stack of sticks and logs is burnt what matter remains?
It was converted to ashes
The wood changed not only to ashes, but also to carbon dioxide, water vapor, and other gases, which floated off into the air, leaving behind just the ashes
They get converted to ashes entirely
They get converted to water vapor, carbon dioxide and other gases
It was completely destroyed
What happened to the wood?
Small pile of ashes
Nothing
A small pile of ashes
Water vapor and other gases before being released to the air
Ashes
What is left when the stack shrinks?
If you build a campfire, you start with a large stack of sticks and logs. As the fire burns, the stack slowly shrinks. By the end of the evening, all that is left is a small pile of ashes. What happened to the matter that you started with? Was it destroyed by the flames? It may seem that way. What do you think happened? The truth is that the same amount of matter still exists. The wood changed not only to ashes, but also to carbon dioxide, water vapor, and other gases. The gases floated off into the air, leaving behind just the ashes. Although matter was changed, it was not created or destroyed. Because the same amount of matter still exists, we can say that matter is conserved. You may wonder how it can be conserved if something is now missing? Assume you had measured the mass of the wood before you burned it. Assume you had also trapped the gases released by the burning wood and measured their mass and the mass of the ashes. What would you find? The ashes and gases combined have the same mass as the wood you started with. This example illustrates the law of conservation of mass.
