Question

use the graph on the right to answer the following questions.
a. estimate the pressure at altitudes of 9,000 feet, 18,000 feet, and 29,000 feet.
b. estimate the altitudes at which the pressure is 23, 19, and 11 inches of mercury.
c. estimating beyond the boundaries of the graph, at what altitude do you think the atmospheric pressure reaches 5 inches of mercury? is there an altitude at which the pressure is exactly zero? explain your reasoning.
b. the altitude for which the pressure is 23 inches of mercury is 8,000 feet, the altitude for which the pressure is 19 inches of mercury is 13,000 feet, and the altitude for which the pressure is 11 inches of mercury is 27,000 feet (round to the nearest thousand as needed.)
c. the altitude at which the atmospheric pressure reaches 5 is approximately 47,000. (round to the nearest thousand as needed.)
explain whether there is an altitude at which the pressure is exactly zero. choose the correct answer below.
a. the pressure reaches zero at an altitude of feet.
b. the pressure approaches zero, but theoretically never reaches zero.

Explanation:

Step1: Analyze graph for part a

Read values from graph for given altitudes.
For 9000 feet, pressure is approximately 20 inches of mercury. For 18000 feet, pressure is approximately 13 inches of mercury. For 29000 feet, pressure is approximately 7 inches of mercury.

Step2: Analyze graph for part b

Given in question: Altitude for 23 inches of mercury is 8000 feet, for 19 inches is 13000 feet, for 11 inches is 27000 feet.

Step3: Analyze graph for part c

Estimate beyond graph for 5 inches of mercury, it is approximately 47000 feet.
As for pressure being zero, in the real - world and based on the nature of the atmosphere, the pressure approaches zero as altitude increases, but theoretically never reaches zero because there are always some gas molecules present in the atmosphere no matter how far out we go.

Answer:

a. 9000 feet: approximately 20 inches of mercury; 18000 feet: approximately 13 inches of mercury; 29000 feet: approximately 7 inches of mercury
b. 23 inches of mercury: 8000 feet; 19 inches of mercury: 13000 feet; 11 inches of mercury: 27000 feet
c. Altitude for 5 inches of mercury is approximately 47000 feet. B. The pressure approaches zero, but theoretically never reaches zero.
