If a gas has a gage pressure of 156kpa, its absolute pressure is approximately what?
A.56kpa
B.256kpa
Thank You
I answered this question yesterday by giving you a site that CLEARLY tells you how to calculate this. You need to read that article. If you don't understand somthing about it, then repost here and tell us what you don't understand. We aren't in the habit of providing the answer carte blanche.
To determine the absolute pressure, we need to add the atmospheric pressure to the gauge pressure. Gauge pressure is the pressure measured relative to the atmospheric pressure, whereas absolute pressure is the total pressure exerted on an object, including atmospheric pressure.
In this case, we are given the gauge pressure of the gas as 156 kPa. To find the absolute pressure, we need to know the atmospheric pressure.
Assuming the atmospheric pressure is approximately 101.3 kPa (which is close to standard atmospheric pressure at sea level), we can add this value to the gauge pressure:
Absolute pressure = Gauge pressure + Atmospheric pressure
Absolute pressure = 156 kPa + 101.3 kPa
Absolute pressure ≈ 257.3 kPa
Therefore, the absolute pressure is approximately 257.3 kPa, which is closest to option B - 256 kPa.
