continued from before....
the question was
what are three chemical characteristics and ten physical characteristics
so then would i have to say something like
-when iron rusts
or
-sugar burns
or something like that
i was thinking that would just be a chemical reaction not a characteristic
Both sugar and iron in your examples are chemical properties. http://en.wikipedia.org/wiki/Chemical_property
thanks :)
Chemical property becomes evident AFTER a chemical reaction has occured.
For example iron has the potential to rust given the right conditions. This is a chemical property.
That is a chemical property.
While a chemical reaction would be like: Iron rusted.
To clarify, a characteristic refers to a distinguishing feature or quality of a substance. In the case of chemical and physical characteristics, chemical characteristics describe the behavior or reactivity of a substance on a molecular level, while physical characteristics relate to observable properties without altering the chemical composition.
Here are examples of three chemical characteristics:
1. Reactivity: Chemical characteristics involve how substances interact and react with other substances. For instance, iron rusting when exposed to oxygen in the presence of moisture is a chemical characteristic.
2. Combustibility: This characteristic refers to a substance's ability to burn. Sugar burning, or undergoing combustion, is indeed a chemical characteristic.
3. Acidic or Basic Nature: Acidity or basicity is a chemical characteristic of substances. For example, lemon juice is acidic, while baking soda is basic.
Additionally, here are ten physical characteristics:
1. Color: This pertains to the visual appearance of a substance.
2. Odor: The scent or smell associated with a substance.
3. Density: The measure of mass per unit volume of a substance.
4. Melting point: The temperature at which a solid substance transitions into a liquid state.
5. Boiling point: The temperature at which a liquid substance transitions into a gaseous state.
6. Solubility: The ability of a substance to dissolve in a liquid.
7. Conductivity: The extent to which a substance allows electrical or thermal energy to pass through it.
8. Hardness: The resistance of a substance to being scratched or dented.
9. Transparency: The degree to which light can pass through a substance.
10. Magnetism: The ability of a substance to be attracted to a magnet.
These examples illustrate the differences between chemical and physical characteristics, as well as provide specific instances for your question.
