What is the absolute pressure inside the ball?
The absolute pressure inside the ball is 1.25atm.
Calculating Absolute Pressure
To calculate the absolute pressure inside the ball, we need to consider the given data:
- Volume, V = 5.27 liters
- Temperature, T = 27.0°C
- Gauge Pressure, Pg = 0.25 atmosphere
- Atmospheric Pressure, Patm = 1.00 atmosphere
Given:
Volume, V = 5.27 L
Temperature, T = 27°C
Gauge Pressure, Pg = 0.25 atm
Atmospheric pressure, Patm = 1 atm
Absolute pressure, Pabs = ?
Calculating Absolute Pressure:
We know the formula for absolute pressure:
\[ P_{\text{abs}} = P_{\text{g}} + P_{\text{atm}} \]
Substitute the given values:
\[ P_{\text{abs}} = 0.25 \text{ atm} + 1 \text{ atm} \]
\[ P_{\text{abs}} = 1.25 \text{ atm} \]
Therefore, the absolute pressure inside the ball is 1.25 atmospheres.
