Answer :
To find the absolute pressure of a gas when the gauge pressure is given, you need to add the atmospheric pressure to the gauge pressure. Gauge pressure is the pressure relative to atmospheric pressure, so for this calculation, you use the following formula:
[tex]\[ \text{Absolute Pressure} = \text{Gauge Pressure} + \text{Atmospheric Pressure} \][/tex]
1. Gauge Pressure: You are given the gauge pressure as 114 kPa.
2. Atmospheric Pressure: Standard atmospheric pressure is typically approximated as 100 kPa for simplicity in calculations like this one.
3. Calculation: Now, add the gauge pressure to the atmospheric pressure:
[tex]\[ \text{Absolute Pressure} = 114 \, \text{kPa} + 100 \, \text{kPa} = 214 \, \text{kPa} \][/tex]
Therefore, the absolute pressure of the gas is 214 kPa.
The correct answer is B) 214 kPa.
[tex]\[ \text{Absolute Pressure} = \text{Gauge Pressure} + \text{Atmospheric Pressure} \][/tex]
