The gauge pressure reading of an automobile tire is 210 kPa. The absolute pressure of the tire is
A) 110 kPa.
B) 210 kPa.
C) 310 kPa.
D) 410 kPa.

Question

Quizplus · Accepted Answer

Gauge pressure is the pressure relative to atmospheric pressure. Since atmospheric pressure is approximately 101 kPa and the gauge pressure is 210 kPa, the absolute pressure is the sum of the gauge pressure and atmospheric pressure, which is 210 kPa + 101 kPa = 311 kPa, rounding to the nearest option gives 310 kPa.
