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. 112.6 kPa E. 225.2 kPa
1 answer:
Answer: C. 25.6 kPa
Explanation:
The Gauge pressure is defined as the amount of pressure in a fluid that exceeds the amount of pressure in the atmosphere.
As such, the formula will be,
PG = PT – PA
Where,
PG is Gauge Pressure
PT is Absolute Pressure
PA is Atmospheric Pressure
Inputted in the formula,
PG = 125.4 - 99.8
PG = 25.6 kPa
The gauge pressure inside the container is 25.6kPa which is option C.
