Select the correct answer.



The gas in a sealed container has an absolute pressure of 125.4 kilopascals. If the air around the container is at a pressure of 99.8 kilopascals, what is the gauge pressure inside the container?



A. 1.5 kPa

B. 24.1 kPa

C. 25.6 kPa

D. 1126 kPa

E. 225.2 kPa

Answer :

To determine the gauge pressure inside the container, we use the following relation:

$$
\text{Gauge Pressure} = \text{Absolute Pressure} - \text{Atmospheric Pressure}
$$

The absolute pressure is given as $125.4\,\text{kPa}$ and the atmospheric pressure is $99.8\,\text{kPa}$. Substituting these values, we have:

$$
\text{Gauge Pressure} = 125.4\,\text{kPa} - 99.8\,\text{kPa} = 25.6\,\text{kPa}
$$

Thus, the gauge pressure inside the container is $25.6\,\text{kPa}$.

The correct answer is:

C. $25.6\,\text{kPa}$
