Answer :
To determine the absolute pressure, we use the relationship between gauge pressure and atmospheric pressure. The formula is given by:
$$
P_{\text{abs}} = P_{\text{gauge}} + P_{\text{atm}}
$$
In this problem, the gauge pressure is given as $156$ kPa and the atmospheric pressure is taken to be approximately $100$ kPa. Substituting these values into the formula, we have:
$$
P_{\text{abs}} = 156\ \text{kPa} + 100\ \text{kPa} = 256\ \text{kPa}
$$
Thus, the absolute pressure is approximately $256$ kPa.
The correct answer is:
A) $256$ kPa.
$$
P_{\text{abs}} = P_{\text{gauge}} + P_{\text{atm}}
