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.

∙ 14y agoA 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 evaparation a physical or chemical change?
Physical. If water evaporates, it is still water. It does not change into a different substance. A Chemical change is when something changes into a different substance. For example, when wood is burned, it changes into a different substance(ash).
How is physical. change different than a chemical. change?
physical changes can be not permanent like solid-liquid-vapour chemical changes are permanent if not reversible

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.
Are state changes chemical or physical changes?
Physical Changes
What Is the between physical changes and chemical change?
Physical changes is change in property. Ex) change from solid to liquid....ice to water. Chemical change changes to different substances. Ex) rotting of fruit.
Are all physical changes accompanied by chemical changes?
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
Why are chemical changes different from physical changes?
Chemical changes cannot be changed back to how they originally whereas physical changes is only the appearance has changed and can be changed back to their original state e.g chocolate (cam be melted and then hardened)
What is the differnce between physical and chemical change?
Chemical changes alter the chemical makeup of a substance... physical changes only change the way something looks, it does not modify the chemical properties.
Chemical changes can be reserved by physical change?
No, chemical changes can only be reversed by chemical means, not by physical means.
Compare the total amount of energy before and after physical and chemical changes?
Physical Change-- Same amount of energy, but in different form Chemical Change-- Different amount of energy, and in a different form
