Why is it necessary to consider the physical properties of a material?
material's performance depends on its physical properties
Is poor conductor of electricity chemical or physical property?
It is a physical property. Changes that occur in a material without changing the identity of the material are physical changes.
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.
When one material turns into a different material with different properties?
physical properties
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
Is a solution a chemical or physical?
A solution is a material not a change; dissolving is a physical process.
Do all objects have physical properties?
All material objects have physical properties.
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 is a physical possessions?
material things that you own
Is hard material physical property?
Yes
What is instructional material in physical education?
sigera
What is the bases for distinguishing between a physical property and a physical quantity?
A physical property of a material is an intrinsic characteristic of this material; examples: density, hardness, refractive index, boiling point etc. This not depends on the material mass. The physical quantity is a measure of the property; examples: g/cm3, volt, pascal, coulomb etc.
