Do all samples of a substance have different physical properties?
Yes, two substances can have the same physical property. For example, both water and ethanol are clear. For this reason, multiple properties must be examined when determining the identity of a substance.
Why are all samples of a given substance have the same intensive properties?
The properties of a pure substance do not vary from sample to sample because there is no reason for them to. Why would they? Water is water, and if you take any sample of water from any stream, lake or ocean and remove all the "stuff" in it to leave only the water, all the samples will behave the same way physically and chemically. The chemical properties of a substance (and the physical ones, too) are set by what the substance is. And these properties define the way the substance behaves in the universe as a whole. There is no reason for any water found on, say Mars, to behave any differently than any water here on Earth - or anywhere else in the universe.
Why does samples of platinum and copper can have the same extensive properties but not the same intensive properties?
Samples of platinum and copper can have the same extensive properties but not the same intensive properties for a couple of reasons. These are both metals but have differing numbers of electrons.
Which is not a characteristic of a compound-?
Different samples of a compound do not have different properties.
What does it mean to say that a solution is homogeneous?
Homogeneous means that a material is the same throughout. Samples taken from any part of the material will be identical to one another. Elements and compounds are homogeneous pure substances. Solutions are homogeneous mixtures.
If two samples of matter had completely identical sets of properties what important inference could be made about the two samples?
Nova net answer: They are the same
Why can samples of gold and copper have the same set of physical properties but not the same set of chemical properties?
They do not have the same set of physical properties. At the very least they have different melting and boiling points, and different densities, and their colors are not identical.

How can you use Dalton's atomic theory to explain why every sample of pure substance has the same properties?
Dalton's atomic theory states that a pure substance is made up of tiny particles called 'atoms', and that each atom of a substance will be identical in shape, size and behavior to any other atom of that substance, regardless of source or location. Any two samples of a pure substance will demonstrate the same properties because all of these samples are comprised of identical atoms which behave identically.

How does drying of soil samples affect the soil properties?

Suppose you have two mineral samples with the same hardness What other mineral properties could you use to decide whether the two samples are the same mineral?
color, refractive index, thermal conductivity, electrical conductivity, cleavage, density, fluorescence, radioactivity, reaction with acids or other chemicals, chemical composition, etc.
What is the samples of compounds?
A sample is a small portion from a material.
Samples of both properties physical properties?
Physical- Something PURE. Chemical- Something that contains OTHER things.
