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.

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.
True or false the density of a substance is the same for all samples of substance?
False :3
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.
If 2 pure substances have the same density are they same substance?
No, at a different temperature and pressure the volume of any substance increases or decrease (depending on Temperature and Pressure). Also the severity of the volumetric change depends on the state of the substance. Because density=mass/volume and the volume changes while the mass doesn't the density WILL change slightly in solid phase, noticeably in the liquid phase and significantly in the gas phase regardless of weather or not the substance is pure
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.

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.)
Should the density of Al be the same for all Al samples?
The density of pure aluminium is the same for all samples.
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.
At room temperature all samples of liquid H2O must have the same what?
Pretty sure its Density
Should density for aluminum be the same for all aluminum samples?
No. Because Al has a large no. of isotopes. (i think 22 isotopes).
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.

Why is it that an half of an object is denser than the whole object?
That's not true at all. The whole idea of density is that it doesn't depend on the size of the sample; big samples and small samples of the same substance have the same density. If the whole object and a piece of it have different densities, then you can bet the composition of the piece is different from the composition of the whole thing. Example: The whole object ... a rock glued to a surfboard ... has low density and floats. One piece of it ... the rock ... has high density and sinks. (Another piece ... the surfboard ... is even less dense than the complete object, and floats even better.)
