Question

The instrument used for the measurement of pressure of gas is called?

Answer 1

Hint: Pressure is defined as the force a substance exerts on another substance per unit area. The force that the gas exerts on the container boundaries is known as the gas pressure. The gas molecules travel around in a random pattern within the given volume. They collide with the surface as well as each other during this movement. Each individual gas molecule has a very small impact that is difficult to imagine. The gas pressure, on the other hand, is the product of the combined effect of all the gas molecules. The strain would increase as the number of collisions increased.

Complete answer:
Pressure gauges are pressure measurement devices, especially those used to measure pressures higher than atmospheric pressure. A barometer is a type of manometer that is used to measure atmospheric pressure. A manometer is a device that calculates the pressure of a gas or vapour; some are made up of a U-shaped tube with a moving liquid column.
Manometers are precision instruments used to measure pressure, which is defined as the force exerted by a gas or liquid per unit surface area due to the effects of gravity on its weight. A sphygmomanometer is the name for this type of manometer.

Note: Manometers are instruments that use an acceptable liquid inside a Mano-metric column to measure the difference in pressure between two completely different points, or to put it another way, between a specific point and the atmosphere.
