Question

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

Answer 1

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.

Answer 2

Answer:

a. extensive, quantitative

Explanation:

Hello,

In this case, since 69.2 kg of a substance is pointing out the exact mass of a substance, we infer that it is about an extensive property since the mass clearly changes if the mass of the substance is modified. Moreover, since a numerical magnitude is given, we also infer this is a quantitative information. Therefore, answer is a. extensive, quantitative.
