* Physical Properties: These are characteristics of a substance that can be observed or measured without changing the substance's chemical composition. Examples include color, density, melting point, and boiling point.

* Chemical Properties: These describe how a substance reacts with other substances or changes its chemical composition. Examples include flammability, reactivity with acids, and oxidation.

Why quick drying is a physical property:

* Quick drying describes how quickly a substance loses moisture or liquid. This is a change in the physical state of the substance (from liquid to gas) and doesn't involve a change in its chemical makeup.

Example:

* A wet towel dries quickly because the water evaporates into the air. The water molecules haven't changed their chemical structure; they've simply changed state from liquid to gas.
