The equation [tex]\( D = \frac{13}{V} \)[/tex] shows that the density of a particular substance equals a mass of 13 grams divided by the volume of the substance. What happens to the density as the volume approaches 0?

A. The density approaches infinity.
B. The density approaches 0.



Answer :

To determine what happens to the density [tex]\( D \)[/tex] as the volume [tex]\( V \)[/tex] approaches 0, consider the equation given:

[tex]\[ D = \frac{13}{V} \][/tex]

Here, [tex]\( D \)[/tex] represents the density, 13 grams is the fixed mass, and [tex]\( V \)[/tex] is the volume of the substance.

1. Initial Observation: The equation shows that [tex]\( D \)[/tex] is inversely proportional to [tex]\( V \)[/tex]. This means that as [tex]\( V \)[/tex] changes, [tex]\( D \)[/tex] changes in the opposite direction.

2. Behavior as [tex]\( V \)[/tex] Approaches 0:
- When [tex]\( V \)[/tex] gets smaller and closer to 0, the denominator of the fraction [tex]\( \frac{13}{V} \)[/tex] becomes smaller and smaller.
- In the limit, as [tex]\( V \)[/tex] approaches 0, the denominator [tex]\( V \)[/tex] approaches 0.

3. Implication for Density [tex]\( D \)[/tex]:
- Since the numerator 13 is a positive constant and does not change, reducing [tex]\( V \)[/tex] to a very small value results in dividing 13 by an increasingly tiny number.
- Dividing by a number very close to zero results in a very large number because any positive number divided by a value approaching zero increases without bound.

Therefore, as the volume [tex]\( V \)[/tex] approaches 0, the density [tex]\( D \)[/tex] approaches infinity. This can be phrased succinctly as follows:

As the volume [tex]\( V \)[/tex] approaches 0, the density [tex]\( D \)[/tex] approaches infinity.
