This is a chemical change.
Photon collision results in development of new matter as conducted by the CERN lab recently.
chemical change or chemical reaction.
If a chemical change has occurred, the chemical composition has changed and new products will have formed, different from the reactants. If a physical change has occurred, the chemical composition does not change and no new products will have formed.
Because you change the composition of the original matter. It is no longer in its original state. Chemical Change- Change in composition; burning, crushing, etc. physical change- changing state, but substance's composition stays same; freezing, boiling, etc
This is a chemical change because there is a molecular change in the composition. A physical change results when the size, shape, phase, texture etc. of a substance changes. Liquid water heated to water vapor is a physical change.
Beating eggs is a physical change because their chemical composition has not changed. They are still raw eggs, but in a different form.
This is a chemical change.
Yes, a chemical change produces new chemicals with properties different from those of the original
Unlike a physical change, a chemical change produces new substances with properties different from those of the original substances.
A physical change is reversible and does not affect the composition of a substance. On the other hand, chemical change is irreversible and permanent. A substance undergoing a chemical change forms a new substance which has different composition than the original substance.
Change the original composition.
Because it becomes in contact with oxygen which combines with the original composition. There fore changing the composition and temperature.
The boiling of silver is a physical change, in order for something to be called a chemical change, something completely new not only form, but chemical composition as well. Boiling silver produces silver gas but it still has the original chemical makeup.
catalyst
no,as its composition changes and it can not be brought to its original state
A physical change is different than a chemical change, because in a physical change, the composition of the matter did not change. While in a chemical change, the composition of the matter did change.SO basically, the composition of the matter does not change is the difference between a physical change and a chemical change.yes
