What is a characteristic property? List 3 characteristic properties
A characteristic property is a physical or chemical property that is unique to a particular substance or material. These properties can be used to help identify or classify substances. Here are three examples of characteristic properties:
1. Density: Density is the measure of how much mass is contained in a given volume of a substance. It is a characteristic property because each substance has a specific density that is unique to it. To determine the density of a substance, you need to know its mass and volume. The formula for calculating density is Density = Mass / Volume.
2. Melting Point: Melting point is the temperature at which a solid substance changes into a liquid state. Different substances have different melting points, so it is a characteristic property. To determine the melting point of a substance, you need to heat it gradually and observe at which temperature it starts to change from a solid to a liquid.
3. Boiling Point: Boiling point is the temperature at which a liquid turns into a vapor state. Like melting point, different substances have different boiling points, making it a characteristic property. To determine the boiling point of a substance, you need to heat it and observe at which temperature it starts to vaporize.
These three characteristic properties are just a few examples, and there are many more, including solubility, conductivity, and reactivity, that are specific to different substances and can be used to identify and differentiate them.
