A monometer measures what?

A monometer measures what?

• A. Pressure of fluid
• B. Temperature
• C. Humidity
• D. Volume

Answer: (A)

Pressure is what a monometer measures. It works by balancing the pressure of the gas or liquid against a column of liquid; the height difference in that column changes as the pressure changes, giving a reading of how much pressure the fluid is exerting (often relative to the atmosphere). This is distinct from temperature, humidity, or volume, which require different instruments to measure. So the monometer’s primary function is to indicate the pressure of the fluid.
