The density of pure aluminium is the same for all samples.
At room temperature, all samples of liquid H2O must have the same boiling point, which is 100 degrees Celsius or 212 degrees Fahrenheit at standard atmospheric pressure.
No, density can vary slightly between different samples of aluminum due to factors like impurities or differences in processing. Generally, the density of aluminum is around 2.7 g/cm3, but small variations are possible.
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.
It could be many things such as temperature or pressure.
When boiling water turns into steam, the temperature remains the same until all the liquid water has boiled off. The phase density decreases as the water converts to steam because steam has a lower density compared to liquid water.
Any sample size of a particular substance will have the same density.
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.)
Yes, density is an intrinsic property of a substance and remains constant regardless of the sample size or quantity. The formula for density is density = mass/volume, and this relationship holds true for all samples of the same substance.

Not necessarily. The temperature of the samples would have to be the same. It can also vary with how pure the substance is.
False. The density of a substance can vary depending on factors such as temperature and pressure. Additionally, impurities in a sample can also affect its density.
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.
Data from random samples will not always include the same values. Values are chosen randomly and they may or may not be the same. So means will vary among random samples.
Both samples have the same density because they are made of the same material, zinc metal. Density is a property of the material and is independent of the quantity of the material present. Density is determined by the mass and volume of the material, not the amount of the material.
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.)
Not at all. The density remains the same.
