no. it is a chemical change.
freezing an ice cube is actually a physical change, and a burnt log is a chemical change because it is a different substance than it was initially (whatever you do you can't make a burnt log a regular non-burned log again).
The logs cellular structure becomes burnt.
Burning the log is a chemical change. All of the others are physical changes.
Splitting a log with an axe is a physical change. The log is being physically divided into smaller pieces, but its fundamental chemical composition remains the same.
It is a physical change, because the wood is still wood but it is in a different form
burnt paper,wet paper
chemical
Do the logs change from wood to some other substance? No, so it has to be a physical change.
Although it has physical consequences, burning a log is a chemical change. The molecules of the log react with oxygen to form carbon dioxide, water steam, and many other products. A simple, fairly reliable test to tell the difference between physical and chemical changes is: Can the process be reversed rather easily? If the answer is yes, like dissolving salt in water, it is a physical change; if no, a chemical change.
Yes, carbon from the log combines with the air to form co2.
chemical change is reversible whereas physical is irreversible e.g a paper after getting burnt cant be converted to paper again this is a physical change
yes
