Answer :
When discussing vacuums, atmospheric pressure is often referenced in inches of mercury (in. Hg) to describe the level of vacuum achieved. A perfect vacuum is a state where there is an absence of any air molecules or gases.
From the options provided, we're searching for the measurement that represents a perfect vacuum. Standard atmospheric pressure at sea level is approximately 29.92 in. Hg. Therefore, a perfect vacuum, which resembles having no atmospheric pressure, would be close to this value.
Given the choices:
- A. 18.8 in. Hg
- B. 17.3 in. Hg
- C. 29.9 in. Hg
- D. 35.9 in. Hg
The closest to creating a perfect vacuum, where there is no air pressure, is:
- C. 29.9 in. Hg
Option C, 29.9 in. Hg, indicates a level where almost all atmospheric pressure has been removed, closely approximating a perfect vacuum.
