in a physical change, no new substance is formed.
for example liquid water. You freeze it, it becomes ice. when you boil it, it evaporates into steam. HOWEVER. Steam, ice, or liquid, it is STILL water.
You only form new substances in chemical changes: cooking/burning food, reacting chemicals etc. : )

A physical change is best defined as?
a process that does not change the chemical composition of a substance. A change in a substance with no new substances being formed
Can you explain the difference between physical changes and chemical changes?
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.
Differences between chemical and physical properties?
In a physical change of matter, no new substances are formed. However, physical properties such as size, shape, color, or phase may change. Dissolving, melting, evaporating and grinding are examples of physical change.As a result of chemical change, one or more new substances with new and different properties are formed. The new substances are different from the original substance. Burning and the rusting of iron are examples of chemical change.
Why are metal alloys an example of a physical change and not a chemical change?
They are a physical change because it is not like burning where a new substance is being formed.
Is a physical change A. an iron bar rusting B. oil floating on water C. a copper skillet tarnishing D. the sublimation of dry ice?
The answer is D; the sublimation of dry ice. A physical change alters one of the physical properties of a substance (e.g. size, shape, color, etc.), but it does not change the substance itself. A chemical change causes new substances to be formed. The new substances have different chemical properties from the original substance. Changes in the state or phase of matter, such as the sublimation of dry ice (solid carbon dioxide), are physical changes because the chemical compositions of the substances do not change. Sublimation is the change of an object from a solid-state directly to a gaseous state.
What is a fact about chemical change and physical change?
chemical change is when during a chemical reaction a new substance will be formed while in physical change no new substances are formed
Are new substances formed in a physical?
No new substances are formed in physical changes. A existing substance may change forms (liquid water may turn to water vapour or ice) but a new substance is never formed.
Is a tree a chemical or physical change?
it's a physical change because no new substances were formed.
When substances are formed that are different from the starting substances has physical change occurred?
A chemical reaction is a chemical change.
Is it true when a physical change that takes new substances are formed?
It is false. When a physical change takes place, the colors, texture, brittleness will change.
Is burning fuel a chemical or physical change?
It's a chemical change because new substances are formed.
Why is mixed sand and water physical change?
because it is reversible and no new substances are formed
Is mixing sand and gravel a physical or chemical change?
It's a physical change
What is the type of matter change in which matter stays the same and no new substances are formed?
In physical change, matter stays the same and its chemical structure is unaffected. However, it's physical look is changed.No new compound is formed in a physical change.
What changes of matter occur in respiration?
A change is said to be physical if no new substances are formed. Physical changes are temporary and can easily be reversed to give back the substances in their previous form. Freezing of water is an example of a physical change. A change is said to be chemical if new substances with different properties are formed. Chemical changes are permanent and cannot be reversed to give back the substances in their previous form. Burning of paper is an example of a chemical change.
Is water evaporating into steam chemical or physical change?
It's a physical change because no new substances are formed, the molecules simply get further apart.
A physical change is best defined as?
