A manometer could also be referring to a pressure measuring device, usually limited to measuring pressures near to atmospheric. The term manometer is often used to refer specifically to liquid column hydrostatic instruments.

What is the instrument that measures changes in air pressure without using a liquid?
An aneroid barometer is an instrument that measures changes in air pressure without using a liquid. It uses a flexible metal box called an aneroid cell that expands and contracts with changes in pressure, which is then translated into a measurement on a dial.
What is the unit of measurement measures atmospheric pressure?
ATM
What is a wet leg?
A wet leg is a section of tubing or piping filled with liquid as part of a pressure measurement system. The liquid communicates pressure to a pressure transmitter for measurement. Wet legs are commonly used in industrial processes to accurately measure pressure.
How will show that the process of evaporation depends on the nature of the liquid?
By the measurement of the pressure vapour at a given temperature; this value is different from liquid to liquid.

What Measures AtMosphere Pressure?
The atmosphere pressure is commonly measured using a device called a barometer. This instrument detects the weight of the air above it, which decreases as altitude increases. The most common unit of measurement for atmosphere pressure is the bar or millibar.
Which is larger 1 mg or 1 ml?
A ml (milileter) is a liquid measurement and mg (miligram) measures weight. They measure different things. Milligrams are measures of mass. Milliliters are measures of volume.
What instrument measures the pressure in an enclosed container of gas?
A manometer is used to measure pressure in an enclosed container of gas. It typically consists of a U-shaped tube filled with liquid that reacts to changes in pressure inside the container. The liquid level in the arm of the manometer connected to the container will rise or fall based on the pressure, providing a measurement of the gas pressure.
A graduated cylinder measures the?
A graduated cylinder measures the volume of liquids in milliliters or cubic centimeters. It is commonly used in laboratories for accurate measurement of liquid volumes.
Difference between pressure gauge and manometer?
A pressure gauge measures pressure in a system relative to atmospheric pressure, displaying the reading in units such as psi or bar. A manometer measures pressure by balancing the weight of a liquid with the pressure being measured, often displaying pressure differentials in terms of inches or millimeters of the liquid column. In summary, a pressure gauge gives absolute pressure readings, while a manometer measures pressure differentials.
What is the purpose of a pressure transducer?
A pressure transducer measures pressure, specifically that of gases or liquids. Such pressure sensors are used in the measurement and control of thousands of everyday applications. A pressure transducer is just that; a transducer - it generates a signal due to the pressure imposed.
How a barometer can be used to measure the vapor pressure of a liquid?
A barometer can be used to measure the vapor pressure of a liquid by placing the liquid in a sealed container connected to the barometer. The pressure inside the container will increase as the liquid evaporates, allowing the vapor pressure to be determined based on the pressure reading on the barometer.
