PRINCIPLES OF PHYSICS by Subramaniam
What else can I help you with?
Why is it necessary to consider the physical properties of a material?
material's performance depends on its physical properties
Can a physical change form a new material?
No, if a new material forms that would be a chemical change. Physical changes always remain with the same material you began with.
Is malleability a physical or chemical change?
Malleability is a physical property of a material, not a change. It refers to the ability of a material to be hammered or pressed into a different shape without breaking.
What evidences a physical change?
"A physical change occurs when some of the properties of a material change, but the substances in the material remain the same." "...any actions that change the size and shape of a material, but not its composition." if the shape/form is changed but not its makeup, then that change is physical
When one material turns into a different material with different properties?
physical properties
Is poor conductor of electricity chemical or physical property?
Poor conductivity of electricity is a physical property, as it is determined by the material's ability to allow the flow of electric current. This property depends on the arrangement and behavior of the material's electrons, rather than its chemical composition.
Is brittleness chemical or physical propertie?
Being brittle is a physical property.
Is a solution a chemical or physical?
A solution is a material not a change; dissolving is a physical process.
Why is density is a useful physical property for identifying substances?
Density is useful for identifying an unknown material because it is a physical constant. A physical constant is a unique characteristic of the material in question. This constant never change or vary with the shape or amount of the material/substance.
What name do we give to temporary changes to a material?
Temporary changes to a material are known as physical changes. These changes do not alter the chemical composition of the material but only its physical properties such as shape, size, or state.
Which physical property is shown by scratching one material with another?
The physical property shown by scratching one material with another is hardness. Hardness is a measure of how resistant a material is to scratching or indentation.
Is conducting electricity a physical or chemical property?
Conducting electricity is a physical property of a material, as it involves the movement of electrons within the material in response to an electric field. A material's ability to conduct electricity is determined by its atomic structure and how freely electrons can move within it.
