What is the difference between gauge pressure and absolute pressure?
A. Gauge pressure is relative to atmospheric pressure, while absolute pressure is measured relative to a vacuum.
B. Gauge pressure is measured relative to a vacuum, while absolute pressure is relative to atmospheric pressure.
C. Gauge pressure and absolute pressure are the same thing.
D. Gauge pressure is only used for liquids, while absolute pressure is only used for gases.
Answer:A
What is the difference between gauge pressure and absolute pressure?
A. Gauge pressure is relative to atmospheric pressure, while absolute pressure is measured relative to a vacuum. B. Gauge pressure is measured relative to a vacuum, while absolute pressure is relative to atmospheric pressure. C. Gauge pressure and absolute pressure are the same thing. D. Gauge pressure is only used for liquids, while absolute pressure is only used for gases.
Explanation: Gauge pressure is measured relative to atmospheric pressure, while absolute pressure is measured relative to a perfect vacuum (zero pressure). Absolute pressure is typically used in scientific and engineering applications, while gauge pressure is more commonly used in everyday applications.
