Is cutting a log into boards a physical property chemical property chemical change or physical change?
Cutting a log into boards is a physical change. This is because the chemical composition of the log remains the same before and after cutting, only its physical appearance has changed.
Is burning a log a example of chemical or physical changes?
Burning a log is an example of a chemical change because the process involves a chemical reaction between the wood and oxygen resulting in the formation of new substances such as ash and gases. This change cannot be reversed, unlike physical changes which only affect the physical state of a substance.
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.
Why does burning a log in the fireplace involve a chemical reaction while sawing a log in half does not?
Burning a log in the fireplace involves a chemical reaction because it undergoes combustion, reacting with oxygen to produce heat, light, and new chemical compounds like carbon dioxide and water vapor. Sawing a log in half is a physical change where the log is simply being cut into smaller pieces without any chemical reactions occurring.
Is cutting a stack of wood from a log a chemical change?
No, it is a physical change. If you think about cutting the wood, the pieces will be smaller than the log, but they will have all of the same properties as they did when they were put together. An example of a chemical change is burning the wood. The act of burning it would be a chemical change since it is converting the wood into carbon and water vapor.
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.
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.
Is it a physical change when a log is burnt?
no. it is a chemical change.
Is cutting a log into boards a physical property chemical property chemical change or physical change?
Cutting a log into boards is a physical change. This is because the chemical composition of the log remains the same before and after cutting, only its physical appearance has changed.
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?
Burning a log is an example of a chemical change because the process involves a chemical reaction between the wood and oxygen resulting in the formation of new substances such as ash and gases. This change cannot be reversed, unlike physical changes which only affect the physical state of a substance.
When you burn a log has a physical change occurred?
Yes, carbon from the log combines with the air to form co2.
When a log burns in a fire is a physical change taking place?
yes
Is A log burned leaving ash a physical change?
No, it's a chemical change. A physical change is one which can be reversed. Like ice to water to ice etc.
A popsicle melting is physical or chemical change?
Melting is a physical change.
