How does an aneroid barometer measure atmospheric pressure?

A barometer is an instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury.An aneroid barometer is a barometer which measures pressure without using fluids!An aneroid barometer is somewhat different and uses a sealed chamber upon which the fluctuating atmospheric pressure acts. Through mechanical means a pointer is moved on a calibrated scale.


What is the mass of an evacuated chamber?

The mass of an evacuated chamber is the mass of the chamber. If you are asking about the mass of the volume of the evacuated chamber, then it is zero.

What is an evacuated chamber?

It is a chamber that consits of no particles and its inside, therefore, is a vaccum. (Get it? Evacuated > Vaccum).The volume inside of an evacuated chamber is zero and is used so an experiment conducted inside of it has little risk of being effected by particles. So in Rutherford's experiment, they use it so no gas particles/atoms/nuclei can get in the way of the alpha radiation which gets absorbed by the air after 5cm of travel and has such a large size and mass so the experiment has big chance of being affected by air particles.Hope this helps :),x BBC Merlin Fan
