* Physical Properties: These are characteristics of a substance that can be observed or measured without changing the substance's chemical composition. Color, hardness, texture, and taste all fall into this category.

* Chemical Properties: These describe how a substance reacts with other substances or changes its composition.

Let's look at why the other options are incorrect:

* Ionic: This refers to a type of chemical bond, not a property of matter.

* Volumetric: This relates to volume, which is a physical property, but it's not the most accurate description of the listed properties.

In summary: Color, hardness, texture, and taste are all physical properties of matter because they can be observed or measured without changing the substance itself.
