Characteristic Property of Substances (mass, volume, and density)

[kevinli]

Homework Statement

A characteristic property is a property that can be used to help identify a substance since it is the same for all samples of the substance. We have now studied mass, volume and density. Which of these is a characteristic property of substances? Explain.

I think it is density, but I am not sure why. Thank you for helping me.

You are correct in saying density is a characteristic property of material.

Density ([tex]\rho[/tex]) = mass (m)/volume (V)

so the density is a ratio of a material's mass to it's volume.

Example: Water
If you have 1L of water it would weight 1000g (1kg)

If you had 1m³ of water it would weigh 1,000,000 g (1000 kg)

Even though the weight and the volume of these 2 amounts of water are different, the density of them both is still 1 g/cm³ or 1000 kg/m³ (Those the same value with different units)

So the density doesn't change for any given material and therefore that makes it a characteristic property of the material.

I hope this helps you!

Cheers

You are correct, density is a characteristic property of substances. Density is defined as the mass of a substance per unit volume, and it is a unique value for each substance. This means that no matter how much of a substance you have, the density will remain the same. This makes it a useful property for identifying substances, as you can compare the density of an unknown substance to known values to determine its identity. Mass and volume can vary for the same substance depending on the amount of the substance present, so they are not considered characteristic properties.
