(3) Write in brief about barometre.
Answers
Answer:
A barometer is a device that is used to measure atmospheric pressure. It can also be used to measure altitude or height, because atmospheric pressure changes with change in distance from the sea level. The atmospheric pressure measured by the barometer is known as barometric pressure.
Answer:
Explanation:
A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. The atmosphere is the layers of air wrapped around the Earth. Meteorologists use barometers to predict short-term changes in the weather.

A barometer is a scientific device that is useful to measure air pressure in a given environment. Pressure tendency can give the forecast short term changes in the weather. Many measurements of the air pressure are in use within the surface weather analysis. It is to help for finding the surface troughs, pressure systems and frontal boundaries. It is a scientific instrument useful to measure the atmospheric pressure which is termed as barometric pressure. In our atmosphere, many layers of air are wrapped around the Earth. This air is having the weight and presses against everything it touches as gravity pulls it to Earth. The barometer is applicable hereto measure this pressure. This article will discuss many aspects of this device in a systematic way.
