A process in which the reactants form products with different chemical compositions is generally a chemical change. It is also often harder to change the products of a chemical reaction back into the reactants, than it is for a physical change. For instance, burning a log would be a chemical change; you don't have wood after you burn the log, you have carbon dioxide, soot, etc., and you can't get the wood back by reversing the process.

∙ 13y agoThe process that produces a chemical change is when to chemicals react to each other and may, therefore, have a change of state (but not always).

Is transferring graphite from pencil to paper when writing a chemical or physical change?
physical change. You know that it is a physical change because it can be reversed. An example of a chemical change would be cooking an egg. Because you cannot reverse the process.
Are exploding fireworks an example of a physical or chemical change?
Explosions are a form of either combustion or decomposition (or both) reactions, and they are chemical changes.
Is a solid breaking up into many pieces a chemical change?
Disintegration can be a chemical change, but it depends on what kind it is. For example, sharpening a knife is a physical change, but burning a piece of wood is a chemical change.
Is combustion a physical change or a chemical change?
Combustion is basically a chemical reacting with oxygen to become the oxide and water is produced. So when alcohol combusts, for example, it is changed (burned) to carbon dioxide and water. In other words, there is a chemical change.
Is ripening fruit a physical or chemical change?
Involving chemical reactions it is a chemical process.
What is an example of physical rather that a chemical change?
Melting is a physical process.
What is an isoentropic process?
An isoentropic process is a chemical or thermodynamic process in which entropy does not change. An example a reversible adiabatic process is isoentropic.

Chemical change?
The process of changing into entirely new substances.
What is an example of a change from electrical energy to chemical energy?
The process of charging a storage battery.
Are exploding fireworks an example of a physical or chemical change?
Explosions are a form of either combustion or decomposition (or both) reactions, and they are chemical changes.
Is digestion of a candy bar a physical change or chemical change?
Chemical property
What is an example of an chemical change?
Chemical reactions also known as chemical change occurs when new products are produced due to the reorganization of atoms. The best example for this process is the change from raw food to cooked food.
Which process is an example of a physical change?
Dissolving salt in water and making ice cubes
Is a solid breaking up into many pieces a chemical change?
Disintegration can be a chemical change, but it depends on what kind it is. For example, sharpening a knife is a physical change, but burning a piece of wood is a chemical change.
Is evaporation a chemical or a physical?
Evaporation is an example of a physical change, as the chemical composition of the substance is not altered in any way.
Is snow melting when salt is added a chemical or physical change?
Melting of ice with salt is example of physical change as there is no chemical reaction involved .
