No, not always. For example, if you mix salt and water, no chemical change takes place. The salt dissolves in the water and a solution is formed, which is not a chemical change because the salt and water retain their individual chemical compositions.
A change in the atomic makeup of the substance.
Changes in composition, or what things are made of.
Heating can cause chemical changes, but it depends on what you are heating. Heating in and of itself is a physical change.
A chemical reaction is a chemical change.

It's a chemical change: heat alters the protein bonds in the egg.
The chemical change causes the color change when the two new chemicals combine.
The chemical change causes the color change when the two new chemicals combine.
Yes. Specifically it involves the Maillard reaction, which is what causes browning.
Definitely a chemical change. This causes a manipulation in the substance's properties and chemical behavior.
It is true that a chemical reaction causes a chemical change. An example of this can be seen by adding baking soda to vinegar.
Souring milk causes a chemical change because it changes its state of matter (from a liquid to a semi-solid), and it grows bacteria. When milk sours it causes a permanent change, therefore making it a chemical change.
a chemical reaction
chemical change
Yes. The charging causes a chemical change in the electrolyte of the battery.
Nope. It's a physical change.
For example a mechanical deformation which not imply a chemical reaction.
It's a chemical change. A chemical change is any change that causes a substance to change into another substance. A sign to know whether it's a chemical change or not, are the changes in odor. When something decays the change in smell is very powerful. Therefore, it is a chemical change.
It is a chemical process. The diesel gets compressed with air which in turn causes heat which in turn causes combustion.
Physical changes are changes affecting the form of a chemical substance, but not its chemical composition.
