briefly describe the working of barometer
Answers
Answer:
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. That air has a weight and presses against everything it touches as gravity pulls it to Earth. Barometers measure this pressure.
Answer:
going to rain today? Is it going to stay fine? And how can you tell? One easy way is to measure the air pressure. If it's rising and the pressure is high, chances are it'll be a fine day; if the pressure is falling, it's more likely to be wet, windy, and dull. Instruments that measure air pressure are called barometers and people have been using them for weather forecasting and scientific research for hundreds of years. Let's take a closer look at how they work!
