A vacuum gauge of a chamber reads -300 mm H₂O. Determine the absolute pressure of the chamber in kPa when the atmospheric pressure is 100 kPa.

(Hint: 1 kPa = 102 mm H₂O).

a) 100.98 kPa
b) 99.02 kPa
c) 102 kPa
d) 200 kPa

Answer :

Final answer:

To determine the absolute pressure of the chamber in kPa, convert the vacuum reading from mm H₂O to mm Hg and then to kPa using the appropriate conversion factors.

Explanation:

To determine the absolute pressure of the chamber in kPa, we need to convert the vacuum reading from mm H₂O to kPa. First, we convert the vacuum reading from mm H₂O to mm Hg by adding 760 mm Hg to -300 mm H₂O. This gives us a result of 460 mm Hg. Then, we convert mm Hg to kPa using the conversion factor 1 kPa = 102 mm H₂O. Thus, the absolute pressure of the chamber is 460 mm Hg x (1 kPa / 102 mm Hg) = 4.51 kPa.
