A chemical change is one that creates compounds (products) that are different from the reactants.
A physical change only alters the form or phase of the existing substances, not their chemical properties.
There are 2 kinds of changes,they are physical and chemical changes.Physical Change-is a change in the form of matter but in it's identity.Chemical Change-is a change in which one kind of matter is changed in to a different type of matter.
Exothermic reactions. E.g. combustion, oxidation
A chemical change is when an obect change to a different kind of matter.
A change in some properties of matter without forming a different kind of matter is called a physical change. This can involve changes in state, shape, size, or appearance of the substance, but the chemical composition remains the same.

Nuclear and Chemical changes result in new substances.

It is a physical change.
A chemical change is a transformation where substances are converted into different kinds of matter with new properties. This involves the rearrangement of atoms and the formation of new chemical bonds. An example of this is when hydrogen and oxygen combine to form water.
A pure substance contains only one kind of matter. It cannot be separated into other substances by physical means.
Exothermic reactions. E.g. combustion, oxidation
A chemical change is when an obect change to a different kind of matter.
It is a chemical property. A chemical property is a characteristic of matter that allows it to change to a different type of matter.
A change in some properties of matter without forming a different kind of matter is called a physical change. This can involve changes in state, shape, size, or appearance of the substance, but the chemical composition remains the same.
