Question

Daniel was out camping, playing his guitar and watching the logs burn in the fire all night long, until he fell asleep. The next morning, Daniel wanted breakfast, but noticed all the logs from the campfire turned to gray ashes.

Daniel exclaimed, "The logs are gone! The fire has disappeared!"

What could have happened to all of the logs in the camp fire?

Think…
· What type of change in matter is this?
· Why were there only ashes left?
· Can Daniel turn the ashes into logs again?
· Are the ashes just as heavy, as the logs?

Answer 1

Answer: It's a chemical reaction.

Step-by-step explanation:

Wood being burned up to the point it turns into ashes is a chemical change of when wood is in the presence heat. No, the ashes will not be as heavy as they used to.
