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.
What else can I help you with?
How can you describe the relationship between mass and volume for these samples?
For substances with constant density, their mass is directly proportional to their volume. This means that as the volume of the substance increases, its mass also increases in a linear fashion. The relationship between mass and volume is described by the density of the substance, which remains the same regardless of the amount of the substance present.
What physical and chemical properties would you expect to find in two different samples of a pure substance?
Two different samples of a pure substance would have the same physical properties, such as color, melting point, boiling point, and density. Their chemical properties, like reactivity and ability to form specific compounds, would also be identical. Variations in the samples' properties could indicate impurities present.
Should the density of Al be the same for all Al samples?
The density of pure aluminium is the same for all samples.
What are some ways the density of a substance can be increased and decreased?
The density of a substance can be increased by compressing it or increasing its mass without changing its volume. It can be decreased by expanding it or reducing its mass without changing its volume. Temperature changes can also affect density, with most substances expanding when heated and contracting when cooled.
Does the same volume of all dry substances weigh the same?
No. The weight of a given volume of a solid is dependent on its DENSITY (weight per volume). The value provided may be its absolute density (at a given temperature) or its specific gravity(density compared to another substance, usually water).
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 do two samples with the same substance with the same volume HAVE to have the same mass?
Because they are of the same substance they have the same density density = mass/volume
Is it true that the density of a substance is the same for all samples of the substance?
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.
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.
What is the effect of shape on the density of samples of the same material?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
True or false the density of a substance is the same for all samples of substance?
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.
The density of an substance varies with samples of that substance?
Yes, the density of a substance can vary depending on factors such as temperature, pressure, and the purity of the material. Small differences in the arrangement of molecules or the presence of impurities can lead to variations in density between samples of the same substance.
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.)
Under the same conditions of temperature and pressure three different samples of the same uniform substance will have the same?
Density reason is that the density of a uniform material is constant Density is independent of the size and shape of the sample.
What cube has a greater density 35 centimeters or 70 centimeters?
If they both have the same substance inside, then they both have the same density. If they don't both have the same substance inside, then we have to know what the substances are before we can figure out anything about the density of the cubes. Size has nothing to do with density.
