Answer:
B. 8.25 atm
Step-by-step explanation:
To calculate the gauge pressure inside the container, we need to understand the concept of gauge pressure and how it relates to absolute pressure.
Gauge pressure is the pressure measured relative to atmospheric pressure. It represents the pressure above or below atmospheric pressure. Absolute pressure, on the other hand, is the total pressure exerted by a gas, including atmospheric pressure.
In this case, the gas inside the container has an absolute pressure of 9.25 atmospheres. The air around the container is at standard pressure, which is typically defined as 1 atmosphere.
To find the gauge pressure, we subtract the atmospheric pressure from the absolute pressure. In this case, the gauge pressure can be calculated as:
Gauge pressure = Absolute pressure - Atmospheric pressure
Gauge pressure = 9.25 atmospheres - 1 atmosphere
Gauge pressure = 8.25 atmospheres
Therefore, the gauge pressure inside the container is 8.25 atmospheres.
It's important to note that gauge pressure is a relative measurement and can be positive or negative depending on whether the pressure is above or below atmospheric pressure. In this case, the gauge pressure is positive, indicating that the pressure inside the container is higher than atmospheric pressure.
