Read another resource to learn more about simple everyday chemical reactions. They create new substances as a result of chemical reactions. While physical changes are sometimes easier to see, chemical changes are more dramatic at the molecular level. The most important thing is to remember when one process stops and another starts. You will find that many everyday processes, especially biological functions, involve both physical and chemical changes. But when your saliva hits these food particles, enzymes begin to break it down, which is a chemical change. The food broken down by your teeth has the same molecular structure as before your first bite, which causes a physical change.

For example, picking a carrot is much easier than melting a block of ice. While all of these processes are physical changes, some are easier to reverse than others. Here are some physical changes you may see: Although it now has a different physical property, it is still the same thing or substance – the molecules are still the same. Physical changes mean that an object or substance changes form or state. Determining whether a change is reversible is a key factor in determining whether a change is chemical or physical. While you can use silver cleaning to remove tarnish with another chemical reaction, you can’t, for example, fry an egg or reverse the process of breaking down dead leaves. Most of these changes are irreversible after chemical reactions. When a chemical reaction occurs, the chemical properties of the original substance change, resulting in a completely new substance.

The molecules of matter have never changed. But when it undergoes a physical change, it only needs to return to its original state. When a substance is chemically changed, it cannot return to its original state without further reactions.
