Answer :
Sure! Let's solve each part of the question step-by-step:
1. Convert 44 mmHg to inHg:
To convert millimeters of mercury (mmHg) to inches of mercury (inHg), we can follow these steps:
- First, convert mm to cm. Since 10 mm equals 1 cm, we divide 44 mm by 10, which equals 4.4 cm.
- Next, convert cm to inches. Since 2.54 cm equals 1 inch, we divide 4.4 cm by 2.54, which gives approximately 1.732 inches of mercury.
So, 44 mmHg is approximately 1.732 inHg.
2. Convert 72 inHg into atmospheres:
To convert inches of mercury to atmospheres, use the conversion factor that 29.92 inHg equals 1 atmosphere.
- Divide 72 inHg by 29.92 to get the result in atmospheres.
- This gives approximately 2.406 atmospheres.
3. Convert 0.83 atmospheres into two other units of pressure:
- To convert atmospheres to mmHg, we use the fact that 1 atmosphere equals 29.92 inHg. Since each inch of mercury can be converted to mmHg using the original two conversions (2.54 cm in an inch and 10 mm in 1 cm), 1 atmosphere ultimately equals 760 mmHg.
- Therefore, multiply 0.83 atmospheres by 760 mmHg to get approximately 630.773 mmHg.
For the conversion to inHg,
- Multiply 0.83 atmospheres by 29.92 inHg to get approximately 24.834 inHg.
4. Calculate the thickness of the stratosphere in miles:
The stratosphere extends from 10 km to 50 km above the ground.
- First, find the thickness in kilometers by subtracting 10 km from 50 km, which gives 40 km.
- To convert kilometers to miles, use the conversion factor that 1 mile equals 1.6 kilometers.
- Divide 40 km by 1.6 to get 25 miles.
So, the stratosphere is approximately 25 miles thick.
