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.

∙ 13y agoTrue, all samples of a substance have identical physical properties. for example, all crystals of sucrose taste sweet and dissolve completely in water.
Wiki User
∙ 15y agoEvery sample of a given substance has the same properties because a substance has a fixed, uniform composition.

∙ 10y agoAll matter has unique physical properties. All matter occupies space and has weight. They also have density which is a physical property. They also have chemical properties.

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.
Which is not a characteristic of a compound-?
Different samples of a compound do not have different properties.
The density of an substance varies with samples of that substance?
that is false because a density is a physical property and as u know physical property can't be changed
How could properties such as color texture and temperature help scientists distinguish between 2 different samples of matter?

Why can gold and copper have the same extensive properties?
Extensive properties have to do with the amount or size of a substance. Gold and copper samples can be made to have the same mass or the same volume, or the same number of moles, or atoms.
Why feather samples weigh more than iron samples?
Because physical properties have a lot more resistance than chemical properties. Thickness is a physical property because it doesn't have reactivity. If I took a shoe and threw it at my friend, he would grow a bump on his head. That would be a physical property. The same thing applies here. A Feather is a chemical substance, and Iron is a physical substance. A Feather is more dense, and has less mass. Iron is less dense, and has more mass. The answer is simple: Different subsctances have different melting points and boiling points, therefore feather samples weigh more than iron samples.
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.
Samples of both properties physical properties?
Physical- Something PURE. Chemical- Something that contains OTHER things.

What physical and chemical properties would you expect to find in two different samples of a pure substance?
Physically I would expect to find the same boiling and melting points, and the same density. Chemically, I would expect the same reactivity with other substances.
The density of an substance varies with samples of that substance?
that is false because a density is a physical property and as u know physical property can't be changed
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.

Is The density of a substance is the same for all samples of the substance?
Not necessarily. The temperature of the samples would have to be the same. It can also vary with how pure the substance is.
