C. A pure substance has "one set of universal properties". What does this mean?
ICE Princess25 [194]

A pure substance has "one set of universal properties". This means they have some of the universal properties in common.

<h3>The definition of universal property</h3>

A characteristic that describes some structures up to an isomorphism is known as a universal property in mathematics, more specifically in category theory.

As a result, independent of the construction technique used, some objects can be described using universal properties. For example, one can define polynomial rings as derived from the field of their coefficients, rational numbers as derived from integers, real numbers as derived from integers, and rational numbers as derived from real numbers.

All of these definitions can be made in terms of universal properties. In particular, the concept of universal property offers a simple demonstration of the equality of any real number structures, requiring only that they satisfy the same universal property.

<h3>What is the universal property of all substances?</h3>

Diamagnetism is a feature that all substances share.
