Chapter 5, Problem 27b,c,d
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. b. atm c. torr d. kPa (kilopascals)
Verified step by step guidance1
Step 1: Understand the given pressure value and the units involved. The pressure is given as 31.85 inches of mercury (in Hg). We need to convert this value into three different units: atmospheres (atm), torr, and kilopascals (kPa).
Step 2: Convert inches of mercury to atmospheres. Use the conversion factor: 1 atm = 29.92 in Hg. Set up the conversion by dividing the given pressure by 29.92 in Hg/atm.
Step 3: Convert inches of mercury to torr. Use the conversion factor: 1 in Hg = 25.4 torr. Multiply the given pressure by 25.4 torr/in Hg to find the pressure in torr.
Step 4: Convert inches of mercury to kilopascals. Use the conversion factor: 1 in Hg = 3.386 kPa. Multiply the given pressure by 3.386 kPa/in Hg to find the pressure in kilopascals.
Step 5: Review each conversion to ensure the correct application of conversion factors and units. This will help verify the accuracy of the conversions.
