Hello, I wanted to know If I came to the coreect answer.
Thank You
If a gas has a gage pressure of 156
kpa, its absolute pressure is approximately?
My answer: 56kpa
(156kpa-100kpa=56kpa)

Here is a good site that tells you that absolute pressusre is gauge pressure + atmospheric pressure.
256
Hello! It seems like you are asking for confirmation on your answer to a question about the absolute pressure of a gas. To determine the absolute pressure, you need to add the gauge pressure to the atmospheric pressure.
In this case, you mentioned that the gauge pressure is 156 kPa. However, you didn't specify the atmospheric pressure. The standard atmospheric pressure at sea level is approximately 101.3 kPa. If the question does not provide this information, you may assume that the atmospheric pressure is the standard value.
To calculate the absolute pressure, you need to add the gauge pressure and the atmospheric pressure. So, if the atmospheric pressure is 101.3 kPa, the absolute pressure would be:
156 kPa (gauge pressure) + 101.3 kPa (atmospheric pressure) = 257.3 kPa
Based on the information you provided, it appears that your answer of 56 kPa is not correct. The correct answer, assuming the standard atmospheric pressure, would be approximately 257.3 kPa.
If you have any further questions or need clarification, please let me know.
