Question

on a day when the barometric pressure is 760 mm hg, a vacuum gauge indicates 500 mm hg. what is the approximate absolute pressure corresponding to the gauge reading?

Answer 1

The approximate absolute pressure corresponding to the given gauge reading of 500 mmHg is 1260 mmHg.

Step-by-step explanation:

The absolute pressure is the sum of the gauge pressure and the atmospheric pressure. In this case, the gauge reading is 500 mmHg and the atmospheric pressure is 760 mmHg. To find the absolute pressure, you add the two together:

Absolute pressure = Gauge pressure + Atmospheric pressure

Absolute pressure = 500 mmHg + 760 mmHg = 1260 mmHg

So, the approximate absolute pressure corresponding to the gauge reading is 1260 mmHg.
