Answer :

To find the absolute pressure when the gauge pressure of a gas is given, we need to consider both the gauge pressure and the atmospheric pressure.

Gauge pressure measures the pressure of the gas relative to atmospheric pressure. To get the absolute pressure, we add atmospheric pressure to the gauge pressure.

Here are the steps to solve the problem:

1. Identify the gauge pressure: This is given as 114 kPa.

2. Understand atmospheric pressure: Typically, atmospheric pressure at sea level is about 100 kPa.

3. Calculate absolute pressure: Add the gauge pressure to the atmospheric pressure to get the absolute pressure.

[tex]\[
\text{Absolute Pressure} = \text{Gauge Pressure} + \text{Atmospheric Pressure}
\][/tex]

[tex]\[
\text{Absolute Pressure} = 114 \, \text{kPa} + 100 \, \text{kPa} = 214 \, \text{kPa}
\][/tex]

Therefore, the absolute pressure is 214 kPa.

The correct answer is:
D. 214 kPa
