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.
The density of a substance is the same for all samples of the substances?
Density is simply the mass divided by volume. This means that it is the amount of the substance in a specific unit of space. Because a pure substance indicates that it is exactly that, a substance made of a specific combination of elements, it will always have the same density because those elements can only take one form in order for it to be pure.
Under what conditions heat can be given to a substance without raising its temperature?
If the substance is in solid condition and at the melting temperature, heat can be given without rising the temperature. Then the substance melts and all the heat will be used in the melting process. Also when the substance is at the boiling temperature you can add heat without rising the temperature. At that point the heat is used to vaporate the substance.
Should the density of Al be the same for all Al samples?
The density of pure aluminium is the same for all samples.
All substances have characteristic properties. If one of these properties can be observed without changing the identity of the substance it must be a?
Physical :)
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.
True or false the density of a substance is the same for all samples of substance?
False :3
Is it true that the density of a substance is the same for all samples of the substance?
No, as density also depends on the state of matter in the sample of the substance.
The density of the substance is the same for all samples of the substance true or false?
Any sample size of a particular substance will have the same density.

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.
Is the density of a substance varies with samples of that substance true or false?
i think that the answer is False because they have nothing to do with each other

Which is more dense 1 mL of water or 50 L of water?
The answer is: No. Density is a property of a substance, and doesn't depend on the size of the sample. Samples of different sizes all have the same density, as long as they're all samples of the same substance, their compositions are all the same, and the conditions are the same in every case. (Samples of ice and water have different density, because the conditions are different.)
Are all voluntary samples bad samples?
No
Is a compound an example of a chemical change?
All samples of a compound have the same composition; that is a chemical reaction that takes place and a new substance is formed. So yes.
