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.

Which process is an example of a physical change?
Dissolving salt in water and making ice cubes
Is setting a piece of paper on fire a example of chemical change?
yes because it changes the physical properties of it as a paper by burning
What is a non example of chemical changes?
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
Is wood being carved an example of a chemical changes?
No that is a physical change
What is an example of a physical change tarnishing rusting burning or melting?
Melting is an example of a physical change because it does not change the chemical composition of the substance undergoing the change. Tarnishing, rusting, and burning are examples of chemical change because they are caused by chemical reactions, which change the chemical composition of the substances undergoing the change.
What is an example of a chemical change wood burning glass breaking water freezing?
The chemical change is the burning wood because the products, carbon dioxide, water, ash, and soot, have different physical and chemical properties. The other changes are physical changes because the physical and chemical properties of the substances did not change.

Dissolving salt in water and making ice cubes
What is a non example of chemical changes?
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.

How will you classify matter as physical or chemical?
Physical never changes what it is; For example if you boil water its physical because you can change it back to water from precipitation, or if you tear a sheet of paper up it's still paper. Chemical- changes it's whole from it can never go back to what it was; Example, burning wood
What are some common example of physical and chemical change that occur in the environment?
Some Physical Changes:> Water Cycle> Tearing of paper> Breaking of glassesSome Chemical Changes:> Photosynthesis ( the process of manufacturing food in plants )> ripening of fruits> burning> cooking
Is burning coal an example of a physical reaction or a chemical reaction?
Chemical. It is called combustion.
Is burning a tortilla chemical or physical change?
Chemical; you are changing the physical properties of the tortilla. Physical would be just warming or cooling it for example
Is the combustion of wood an example of a physical change?
Combustion (burning) is a chemical change.
What changes of matter occur in respiration?
A change is said to be physical if no new substances are formed. Physical changes are temporary and can easily be reversed to give back the substances in their previous form. Freezing of water is an example of a physical change. A change is said to be chemical if new substances with different properties are formed. Chemical changes are permanent and cannot be reversed to give back the substances in their previous form. Burning of paper is an example of a chemical change.
Example of a physical rather than a chemicalchange?
Which of the following is an example of a physical rather then a chemical change? Which of the following is an example of a physical rather then a chemical change?
Is tear a physical or chemical change?
A physical change. A chemical change would be, for example, burning clothes, or dissolving clothes.
