charicter that distinguish one substance from other sustances

1) Melting point: Each substance has a specific temperature at which it changes from a solid to a liquid state. The melting point is a characteristic property that can help identify a substance.

2) Boiling point: Similar to the melting point, each substance has a specific temperature at which it changes from a liquid to a gas state. The boiling point is another characteristic property that can differentiate substances.

3) Density: The density of a substance refers to its mass per unit volume. Different substances have different densities, allowing them to be distinguished from one another.

4) Solubility: The ability of a substance to dissolve in a particular solvent is known as solubility. Different substances have different solubilities, which can help identify them.

5) Color: The visual appearance of a substance can often be used to distinguish it from other substances. For example, copper has a distinct reddish-brown color.

6) Odor: Many substances have unique odors that can help identify them. For instance, ammonia has a strong, pungent odor.

7) Conductivity: The ability of a substance to conduct electricity is known as conductivity. It can help differentiate between conductors (such as metals) and non-conductors (such as plastics).

8) Reaction with other substances: The way a substance reacts chemically with other substances can be used to identify it. For example, some metals react with acids to produce hydrogen gas.

9) Optical properties: Some substances have unique optical properties that distinguish them from others. For instance, diamonds have exceptional clarity and brilliance.

10) Crystal structure: The arrangement of atoms or molecules in a solid substance can be unique to each substance and can help differentiate them.
