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?
In a physical change, the chemical composition of the substance remains the same, but some physical properties like shape, size, or state may change. This means that the substance can be reversed back to its original state without undergoing a chemical reaction.
Do Substance in a mixture keep their own properties?
Yes, substances in a mixture retain their own properties. Each substance in the mixture maintains its chemical characteristics and can be separated by physical methods.
What is separated into pure substances by a physical method?
false
Compare and contrast how do chemical and physical properties differ?
chemical properties deal with how an object or substance reacts to other substances (usually a solution, or gas, or some aqueous medium... any medium really). physical properties deal with the more noticeable stuff like strength, stiffness, toughness (and yes they all mean different things), brittleness, etc. etc.
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.
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.
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 .
Can the chemical properties of a substance be observed without changing the substance?
physical properties
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.
In a physical change some of the physical properties of the substance may be altered and the chemical composition?
In a physical change, the chemical composition of the substance remains the same, but some physical properties like shape, size, or state may change. This means that the substance can be reversed back to its original state without undergoing a chemical reaction.
Antonym physical properties?
Some antonyms for physical properties are abstract properties, immaterial properties, or conceptual properties. These terms describe characteristics that are not related to the physical attributes of an object or substance.
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.
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.
Do Substance in a mixture keep their own properties?
Yes, substances in a mixture retain their own properties. Each substance in the mixture maintains its chemical characteristics and can be separated by physical methods.
What are some really good examples of physical properties of a substance?
Examples of physical properties of a substance include color, density, melting point, boiling point, and solubility. These properties can be observed and measured without changing the chemical composition of the substance.
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.
