Use the equation where p = pressure and V = volume.What happens to the pressure as the volume approaches 0? Explain your reasoning.

Question illustration
Answer:

As the volume (V) approaches 0, the pressure (p) approaches infinity. This occurs because the variable V is in the denominator of the equation p = 8.31/V. As the denominator gets smaller and closer to 0, the overall value of the fraction increases without bound. Mathematically, there is a vertical asymptote at V = 0, and the function is undefined at that specific point since division by zero is impossible.

Answer:

To find the vertical asymptote of the gravitational force function, we examine the denominator, r^2. Setting the denominator to zero (r^2 = 0) shows that there is a vertical asymptote at r = 0. This means that as the distance (r) between two objects approaches zero, the gravitational force between them increases without bound, approaching infinity.

Did your answer include the following?

A
Examine the denominator and find that r2 = 0 when r = 0.
B
Determine that there is a vertical asymptote at r = 0.
C
Conclude that as the distance between the objects approaches 0, the gravitational force between them approaches infinity.
