What are some physical properties are constant for pure substances?
This has lots of answers; some of them are: malleability chemical properties electrical properties color texture I suspect there are more because the size of something rarely changes the intrinsic properties of that something.
In a physical change some of the physical properties of the substance may be altered and the chemical composition?
No. In a physical change, the substance maintains its chemical composition.
Similarities of chemical and physical changes?
Physical properties are characteristics of a pure substance that can be observed without changing it into another substance. Chemical properties are characteristics of a pure substance that describes its ability to change into different substance.
Is ductile and malleable a chemical property or a physical property?
Ductility, the property of a substance to be drawn out into a thin wire is a physical property associated with some metals, such as gold, silver and copper.
What is separated into pure substances by a physical method?
false
Is a pure substance flammable?
Some are flammable and some are not. This depends on the chemical properties of the individual substance. Nonflammable pure substance include helium, water, and gold. Flammable pure substances include hydrogen, hexane, and magnesium.

Would you expect a pure substance to be the same color throughout?
no we cannot everything changes with time even a pure substance looses it's some of the properties after some time so the color also changes .
In a physical change some of the physical properties of the substance may be altered and the chemical composition?
No. In a physical change, the substance maintains its chemical composition.
What is physical propety?
Physical property is a property that a substance has which can be measured. For instance, some properties are melting points or boiling points.
A pure substance is matter that has a fixed what?
A pure substance is a substance that cannot be separated by means of physical separation but only by chemical. It is a change in time.
What physical property identify a substance?
There are many varying physical properties used to identify a pure substance. Some of the most prevalent physical properties are color, odor, density, melting and freezing points and solubility.
What are the difference between a substance's physical properties and its chemical properties?
Chemical properties involve reacting with another substance. IE: burning of magnesium requires oxygen after which it is no longer magnesium. Physical properties do not. IE: metals are malleable, some very malleable, like copper wire can be bent with your hand. BUT it is still copper wire.

What is the smallest quantity that a chemical compound can be divided into and still maintain its chemical properties?
The general answer would be molecule however some molecules prefer to exists as paired molecules and subdividing them would alter some of its chemical properties: a good example of this would be the sugars.
Which term are use to identify pure substances?
Pure substance can be identified as either elements or compounds. Some examples of pure substance that are elements are sulfur and tin. Pure substances that are compounds are sugar and salt.
