So, physical can be changed back to the original state... Chemical cannot (unless you use another chemical change)
So, melting freezing vaporizing and condensation are physical changes. Chemical is like burning something, or adding a reactive compound/ solution and there being a color change, vapor or smell.
There is a bit more to it, but that's the basics.
Chemical changes involve the formation of new substances with different chemical properties, while physical changes do not involve a change in the chemical composition of the substance. Chemical changes are usually irreversible, while physical changes are often reversible by changing the conditions.

A chemical reaction changes the actual substance like when you burn paper you make it ash. A physical change is one where the actual substance doesn't change when you freeze water into ice it's still water just in solid form. (phase changes are physical not chemical changes)

Is reacting a physical change or chemical change?
Reacting can involve both physical changes and chemical changes. Physical changes involve alterations in the physical state of a substance without changing its chemical composition, while chemical changes involve the formation of new substances with different chemical compositions.
Differences between physical changes and chemical changes?
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
What are two kind of changes in matter?
Two types of changes in matter are physical changes and chemical changes. Physical changes involve a change in appearance, such as a change in shape or state, without forming new substances. Chemical changes involve a rearrangement of atoms to form new substances with different chemical properties.
Are the changes in the state of matter chemical changes?
No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
Changes in properties of matter are called?
physical or chemical changes.

Reacting can involve both physical changes and chemical changes. Physical changes involve alterations in the physical state of a substance without changing its chemical composition, while chemical changes involve the formation of new substances with different chemical compositions.
Chemical changes can be reserved by physical change?
No, chemical changes cannot be reversed by physical changes. Chemical changes involve the formation of new substances with different properties, while physical changes only affect the state or appearance of a substance without changing its chemical composition. Once a chemical change occurs, it cannot be undone by a physical change.

Different between physical and chemical change?
In a physical change the object changes appearance but in a chemical change the object turns into something different with different properties.
What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
What is the different of physical change to chemical change?
A physical change is one where just the appearance of something changes and a chemical change is where the genetic makeup of something changes.
What is the differnce between physical and chemical change?
Physical changes are changes in appearance, state, or form of matter without altering its chemical composition. Chemical changes involve the formation of new substances with different chemical properties. Examples of physical changes include melting ice or tearing paper, while examples of chemical changes include rusting of iron or burning wood.
Changes in properties of matter are called?
physical or chemical changes.
Which occurs more often on earth physical changes or chemical changes?
Physical changes occur more often on Earth compared to chemical changes. Physical changes involve alterations in the state or appearance of matter without changing its chemical composition. Examples include changes in shape, size, or state of matter (solid, liquid, gas). Chemical changes involve the formation of new substances with different chemical properties.
Does a chemical reaction change physical properties or chemical?
A chemical reaction changes the chemical properties of substances involved by forming new substances with different chemical compositions. This can result in changes in physical properties such as color, temperature, odor, and state of matter.
