Question

The compressed gas in a sealed container has a gauge pressure of 185.4 kilopascals. If the air around the container is at standard pressure, what is the absolute pressure inside the container? A. 84.1 kPa B. 143.4 kPa C. 184.4 kPa D. 186.4 kPa E. 286.7 kPa

Answer 1

Here we have to choose the absolute pressure inside the container among the given options.

The absolute pressure inside the container is E. 286.7 kPa.

The absolute pressure of a container is the summation of the pressure of the container in vacuum or the gauge pressure and outside air pressure.

So, mathematically we can write:

Absolute pressure = Gauge pressure  + Outside air pressure.

In this container the gauge pressure is 185.4 kilopascals (kPa).

We know the standard air pressure is 101.325 kpa.

Thus the absolute pressure inside the container is (101.325 + 185.4) = 286.7 kPa.

Henceforth,  the absolute pressure inside the container is option E. 286.7 kPa.
