hlo dear friends plz explain What is meant by physical and chemical properties of matter?
Answers
Explanation:
All properties of matter are either physical or chemical properties and physical properties are either intensive or extensive. ... Physical properties can be measured without changing a substance's chemical identity. Chemical properties can be measured only by changing a substance's chemical identity.
Answer:
Here is your answer friend :)
All properties of matter are either physical or chemical properties and physical properties are either intensive or extensive.
Extensive properties, such as mass and volume, depend on the amount of matter being measured.
Intensive properties, such as density and color, do not depend on the amount of the substance present.
Physical properties can be measured without changing a substance’s chemical identity.
Chemical properties can be measured only by changing a substance’s chemical identity.
Terms
extensive propertyAny characteristic of matter that depends on the amount of matter being measured.
chemical propertyAny characteristic that can be determined only by changing a substance’s molecular structure.
intensive propertyAny characteristic of matter that does not depend on the amount of the substance present.
physical propertyAny characteristic that can be determined without changing the substance’s chemical identity.
All properties of matter are either extensive or intensive and either physical or chemical. Extensive properties, such as mass and volume, depend on the amount of matter that is being measured. Intensive properties, such as density and color, do not depend on the amount of matter. Both extensive and intensive properties are physical properties, which means they can be measured without changing the substance’s chemical identity. For example, the freezing point of a substance is a physical property: when water freezes, it’s still water (H2O)—it’s just in a different physical state.
