Final answer:
The ability of one substance to dissolve in another is called solubility, which is a physical property of matter, unlike chemical properties that relate to how a substance interacts with other substances.
Step-by-step explanation:
The property that describes the ability of one substance to dissolve in another substance is solubility. Solubility is a measure of how much of a solid substance remains dissolved in a given amount of a specified liquid under a specified temperature and pressure. This is a physical property of matter, distinct from chemical properties that describe how matter changes form in the presence of other matter, such as flammability or acidity.
In contrast, chemical properties involve a substance's ability to undergo a change that transforms it into a different substance, such as rusting or burning.
