How is a burnt log and a frozen ice cube 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).
What is a physical change for a log?
The logs cellular structure becomes burnt.
Which is not a physical change hitting a log with an axe cutting a log burning a log or hammering a spike through a log?
Burning the log is a chemical change. All of the others are physical changes.
Is splitting a log with an axe a physical or chemical change?
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.
Is cutting a log into boards a physical property chemical property chemical change or physical change?
It is a physical change, because the wood is still wood but it is in a different form
What is a physical change in paper?
burnt paper,wet paper
When a log rots is it a chemical or physical change?
chemical
Is cutting a stack of wood from a log a physical or chemical change?
Do the logs change from wood to some other substance? No, so it has to be a physical change.
Is burning a log a example of chemical or physical changes?
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.
When you burn a log has a physical change occurred?
Yes, carbon from the log combines with the air to form co2.
What is the difference between a chemical change and a physical one?
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
When a log burns is it a physical or chemical change?
When a log burns, it undergoes a chemical change because the molecules in the log are breaking apart and rearranging to form new substances like ash, smoke, and gases. This process involves the combustion of the wood as it reacts with oxygen in the air to produce heat and light.
