Answer:C
What is absolute pressure?
A. The pressure relative to atmospheric pressure B. The pressure relative to a vacuum C. The total pressure in a system D. The pressure difference between two points in a system
Explanation: Absolute pressure is the total pressure in a system, including the pressure due to the weight of the atmosphere. It is measured relative to a vacuum, which is a reference point where the pressure is zero.
