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.
What else can I help you with?
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
Which process is an example of a physical change?
Dissolving salt in water and making ice cubes
Differences between physical and chemical changes?
Well, darling, a physical change involves a change in appearance, like cutting a piece of paper, while a chemical change involves a change in composition, like burning that paper to ash. So, in simpler terms, physical changes are like a makeover, just changing the looks, while chemical changes are like a complete transformation, changing what's on the inside. Just remember, physical changes are skin-deep, but chemical changes go straight to the core.
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.
Are fireworks an example of physical or chemical change?
Chemical change. A good hint for this one is that there is fire involved, which usually means that the chemical itself is being changed. The constituent materials oxidize (burning quickly - explosion - is very rapid oxidization) and form new compounds i.e. the chemicals 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.
Is burning of paper is one example of physical change?
Burning of paper is actually an example of a chemical change, not a physical change. During burning, the chemical composition of the paper changes as it reacts with oxygen to produce new substances like ash, water vapor, and carbon dioxide.
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
Which process is an example of a physical change?
Dissolving salt in water and making ice cubes
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 wood is an example of physical change.?
I think you mean "Is burning a paper a physical change?" Burning a paper is not a physical change. It is a chemical change. Because you can't turn the ashes of the paper into a normal paper again. Examples of physical change: Cutting a paper, sharpening a pencil, writing on a paper... Examples of chemical change: Rotten egg, Rusted steel, molded bread...
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 are the examlpes of chemical change and physical change?
Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax

What are non examples of physical change?
Any idea is a non example of physical change.
