* Characteristic Property: A characteristic property is a feature that is unique to a particular substance and can be used to identify it. It remains constant regardless of the sample size.
* Density: Density is defined as the mass per unit volume of a substance. It's calculated by dividing the mass of a substance by its volume.
* Why it's a characteristic property: The density of a substance is constant at a given temperature and pressure. For example, the density of pure water at room temperature is always around 1 g/mL. This means that no matter how much water you have, its density will always be approximately 1 g/mL.
* Mass and Volume: Mass and volume are extensive properties, meaning they depend on the amount of the substance.
* Mass: The amount of matter in an object. A larger sample of a substance will have a larger mass.
* Volume: The amount of space an object occupies. A larger sample of a substance will have a larger volume.
In summary:
* Density is a characteristic property because it's a ratio of two extensive properties (mass and volume). It allows you to identify a substance regardless of the amount present.
* Mass and volume are extensive properties because they depend on the amount of substance.
