Want this question answered?
Temperature and amount of the substance do not change chemical properties.
no but a mixture can
boiling point --------- Boiling point is a specific characteristic of a substance or element; the mechanical strength, the viscosity, the electrical resistivity are more difficult to be used for a sure identification of a substance.
physical properties
Four physical properties in urinalysis are:- density- smell- color- undissolved particles
its different because physical it bruoght on by us and chemical is different particles from once was a different substance.
Examples of physical properties: density, mass, melting point, electrical conductivity, hardness, etc.Physical properties are measurable characteristics.
The physical properties of a substance are the substance's physical appearance. This includes the color, shape, weight, width, and height.
Temperature and amount of the substance do not change chemical properties.
The physical properties of a pure substance can be used to identify it. A pure substance is an element or a compound, not a mixture.
Physical and chemical properties of matter are useful because they can help you identify that substance. For example paper burns very easily and aluminum doesn't, this is how they can be described individually.
Diamonds are the hardest known naturally occurring substance. Most diamonds are electrical insulators.
a physical change is a change in any physical property of a substance, not in the substance itself
i think Buoyancy and Density are two physical properties that can vary even when the substance with these properties doesn't change.
Examples: density, thermal conductivity, electrical resistivity, thermal expansion, ductility, malleability, hardness etc.
physical property
During a physical change, the matter of what the substance is made out of doesn't change.
