Although a mixture of substances can often be separated by means of differences in physical properties, the resulting parts are not actually simpler. It takes chemical change to make complicated chemicals simpler.
Sometimes you can. Such as rust changing the color of the object because of how water and oxygen mix together. If you are a student ranging in the elementary school grade to the middle school I would urge you to go on to Brain Pop where they explain different types of things. If youre a high school student I'd look in Science.gov for further information.
Yes. For example, blood can be separated into different components by using a centrifuge.
True, such all physical properties help chemists identify the substance.
no but a mixture can
Temperature and amount of the substance do not change chemical properties.

yes chemical properties do change a substance physical properties just change the physical shape or look!!!
no but a mixture can

Differences in physical properties.
The physical properties of a substance are the substance's physical appearance. This includes the color, shape, weight, width, and height.
- distillation - centrifugation - sieving - flotation - electromagnetic separation - filtering - manual sorting - radiometric sorting -etc.
Temperature and amount of the substance do not change chemical properties.
A chemical change involves a change in a substance's chemical properties (characteristics that describe how it interacts with other substances).A physical change involves a change in a substance's physical properties(characteristics that describe certain features one can see with their 5 senses).
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.
a physical change is a change in any physical property of a substance, not in the substance itself
substance
i think Buoyancy and Density are two physical properties that can vary even when the substance with these properties doesn't change.
