Question

State two uses of a barometer.

Answer 1

Hint:A barometer is a scientific device that measures air pressure in a specific area. Short-term weather variations can be predicted using pressure trends.As a set of weights, the barometer operates by balancing the weight of mercury in the glass tube against atmospheric pressure. The level of mercury in the glass tube increases as the weight of mercury is less than atmospheric pressure (high pressure).

Complete answer:
The barometer was invented by Evangelista Torricelli. In Florence, Italy, he developed the first barometer. His technology has a wide range of modern applications, but barometers are particularly useful for weather forecasting and prediction.

A barometer is a device which measures the pressure in the atmosphere. A barometer may also be used to determine altitude since air pressure varies with distance above or below sea level. Mercury and aneroid barometers are the two most common types of barometers.

Uses of Barometer are:
-Forecasting the weather
-Aneroid barometer calibration and testing
-Pressure measurement of aircraft
-Barographs are produced in a variety of ways.
-Altimeters for aircraft are being prepared.
-Fluid Mechanics Application
-Surface temperature monitoring is done using mercury barometers.
-They are used in fluid dynamics, engineering, astronomy, and chemistry, among other fields.

Note:Altimeters and barometers are the same instruments, but they have different purposes. An altimeter is designed to be used at various heights to adjust the atmospheric pressure to the altitude. At the same time, a barometer is held at the same height and measures minor pressure variations caused by temperature and weather elements.
