Question

A typical barometric pressure in Denver, Colorado, is 615 mm Hg. What is this pressure in atmospheres and kilopascals?

a) 0.808 atm, 81.8 kPa
b) 0.808 atm, 615 kPa
c) 0.808 atm, 81.0 kPa
d) 0.615 atm, 81.8 kPa

Answer 1

The typical barometric pressure in Denver, Colorado, of 615 mm Hg is equivalent to approximately 0.809 atmospheres (atm) and 81.9 kilopascals (kPa) after performing the necessary unit conversions.

Step-by-step explanation:

A typical barometric pressure in Denver, Colorado, is 615 mm Hg. To convert this pressure to atmospheres (atm) and kilopascals (kPa), we can use the conversions where 1 atm = 760 mm Hg and 1 atm = 101.325 kPa. First, calculate the pressure in atmospheres:

Pressure in atm = Pressure in mm Hg / 760 mm Hg
Pressure in atm = 615 mm Hg / 760 mm Hg
Pressure in atm ≈ 0.809 atm

Then, convert this pressure to kilopascals using the relationship between atm and kPa:

Pressure in kPa = Pressure in atm × 101.325 kPa/atm
Pressure in kPa ≈ 0.809 atm × 101.325 kPa/atm
Pressure in kPa ≈ 81.9 kPa

Thus, the equivalent pressure of 615 mm Hg in Denver, Colorado, is approximately 0.809 atm and 81.9 kPa.
