which words best describe the following characteristic? 69.2 kg of a substance? a. extensive, quantitative b. intensive, qualitative c. intensive, quantitative d. extensive qualitative

The correct answer is A. Extensive, quantitative

Explanation:

A property is classified as extensive if it varies with the amount of the substance; this applies to mass, which is measured in grams or kilograms, because depending on the size of the sample the mass changes, therefore "69.2 kg" is an extensive characteristic. Besides this, quantitative characteristics or properties are those that can be measured through numbers; this also applies to mass because a specific number of grams or kilograms shows the exact mass in the substance, in this case, the value is 69.2 kg. Thus, this characteristic is both extensive and quantitative.
