Describe what happens to a substance when it goes through a physical change?

As a generalization it will change one or more of its physical properties. To be more specific, the substance will change form or shape. Form meaning phase of matter (solid, liquid, etc...). Shape coud refer to just moving its components around into a different geometrical arrangement, however this gets trickier once you get to the atomic level.

∙ 14y agoIn a physical change no new type of matter is formed. Examples of physical changes include the tearing of paper--the paper is still paper, even though it has changed the sizes of pieces. Other physical changes include changes of state. When water freezes it is still water and when it melts, it is still water. Mixing things toether without burning them can also be a physical change, if you can unmix the parts. Once you add enough heat to cause a chemical reaction and a totally new, permanent matter forms, you do not have a physical change anymore. You have a chemical change. Also chemical reactions with oxygen and some types of matter cause chemical changes. The red rust on a rusty nail is new matter-iron oxide, so rusting is a chemical change.

A substance can be seperated into simpler parts through differences in physical properties?
Mixture
What happens when substances goes through a phase change?
Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
When substances go through a chemical change what happens to the mass'?
The total mass of products is unchanged from the total mass of the reactants, but the masses of particular substances among the reactants or products change.
Is Fog forming an examples of chemical changes?
The formation of fog is a physical change, not a chemical one.
What is a sidewalk warmed by the heat of the sun a chemical or physical change?
It undergoes a physical change because the matter that makes up the sidewalk does not change. THe side walk goes through a chemical and physical change because the heat makes it constrict by shacking the particles just like it happens with food
What happens When a substance goes through a physical change?
The Substances die
Describe what happened to a substance when it goes through a physical change.?
A physical change is one in which the shape, size, appearance or state, of a substance may alter, but its chemical composition remains same.
Is transparency a physical property?
Transparency is a physical property because in no way does it describe the the substance's chemical properties. All transparency is showing is the light that can pass through it, which is a physical property.
Can a substance be separated into physical parts through differences in physical properties?
no but a mixture can
What can be separated into parts through differences in physical properties?
Substance
What happens if light passes through substance?
It depends on whether the substance is transparent, translucent or opaque. A transparent substance allows nearly all the light through. A translucent substance allows some light through. An opaque substance blocks all the light.
A substance can be seperated into simpler parts through differences in physical properties?
Mixture
When a substance goes from a gas to a liquid it goes through a?
Phase change.
What happens after a substance goes through a chemical change?
Yes because when a chemical change happens the substance may not have some of the physical or chemical properties it had once before. An example of htis would be Dry Ice. This would be an example because dry ice was once just ice then they add a chemical and it turns into dry ice.
What happens to a substance's temperature as it god through the change of state?
Its temperature remains constant.
What happens when light passes through a substance near 0 degrees Kelvin?
When light passes through a substance near 0 degrees Kelvin, it bends and becomes deformed.
Is ability to combine with another substance physical or chemical?
The ability to combine chemically through the formation of chemical bonds with another substance is a chemical property.
