Answer 1

Answer:

as I know about barometer consist of a mercury .

it can be made with a clean ,dry, thick walled glass tube of about one metre long .

the working mechanism can be given by:

when there is air pressure the mercury in the glass goes against the air pressure to balance itself .

If the weight of mercury is less than atmospheric pressure then the mercury will rise upwards and vice versa.

I think no need to explain the parts u can do it your self as it consist of testube and mercury as main components.if u want the explanation then use search engines to reshearch.

hope this helped you

comment if got any confusion .
