melting point
The options "melting point," "toxicity," "rusting ability," and "flammability" are all examples of physical properties.
The option "melting point" is an example of a physical property. To determine which option is a physical property, we need to understand what physical properties are. Physical properties are characteristics or qualities that can be observed or measured without changing the composition or identity of a substance.
To find the answer, we should examine each option and determine if it fits this definition.
1. "Melting point" is a physical property since it is the temperature at which a substance changes from a solid to a liquid state without altering its composition.
2. "Toxicity" is not a physical property because it is a measure of how harmful a substance is to living organisms, which is more related to the chemical and biological properties.
3. "Rusting ability" is not a physical property either. It refers to the tendency of a substance to undergo an oxidation process in the presence of oxygen and moisture, which is more related to the chemical reactivity of the substance.
4. Finally, "flammability" is a physical property as it refers to the ability of a substance to catch fire or burn.
Therefore, among the options listed, "melting point" and "flammability" are the examples of physical properties.
