Question

name two instruments based in atmospheric pressure​

Answer 1

Altimeter and Barometer are two devices based on atmospheric pressure...

Answer 2

Answer:

The two instruments based on atmospheric pressure are barometer and syringe.

Explanation:

• An instrument known as a barometer is used to measure atmospheric pressure, also known as barometric pressure.
• The air layers that round the Earth are known as the atmosphere. As gravity drags that air to Earth, it exerts pressure on everything it touches, called atmospheric pressure.
• Syringe is the name for a glass tube having a nozzle and piston for drawing in and ejecting liquid in a narrow stream.
• The pressure inside a syringe decreases as the piston is withdrawn and the nozzle is dipped in a liquid. The liquid is forced up into the syringe by the increased air pressure acting on its surface.

Hence, barometer and syringe helps to study atmospheric pressure.
