Capitolo 6, Problema 27a
The North American record for highest recorded barometric pressure is 31.85 in Hg, set in 1989 in Northway, Alaska. Convert this pressure to each indicated unit. a. mmHg
Guida verificata passo dopo passo1
1. The problem is asking us to convert the pressure from inches of mercury (in Hg) to millimeters of mercury (mmHg).
2. We know that 1 in Hg is approximately equal to 25.4 mmHg. This is a standard conversion factor in pressure measurements.
3. To convert the pressure from in Hg to mmHg, we simply multiply the given pressure by the conversion factor. In this case, we multiply 31.85 in Hg by 25.4 mmHg/in Hg.
4. The units of in Hg will cancel out, leaving us with the pressure in mmHg.
5. The result of this multiplication will be the pressure in mmHg.
