101325 pascal's joules bhee kuch kuch aisa hee hota hain joule and pascal main kya relationship hain

[@anilkumarsharma1205]

if take water and 100 meter dia vessel and 20 meter long, so we can easily produced very large vacuum chamber and when slightly different atmospheric pressure increases or decreasing then huge amount of water going inside or outside the vessel, this cycle will gives us very high potential energy so we used it for turbine turning by help of spring based battery gearbox

Respected sir, Can we measure height using barometer?

[@IshitaSrivastava21]

Sir please could you tell why is there a point of time where atmospheric pressure becomes equal to the pressure exerted by the mercury since the isn’t even any change in temperature

[@husandeepkaur9015]

does mercury height olways remain 760 cm is it constant

[@DileepSingh-xq6ti]

sonika sandhu it changes place to place and time to time

[@black_jack_meghav]

sonika sandhu it would be 760 cm at sea level. At sea level the atmospheric pressure is about 10 raised to 5 pascals and that is when mercury column would be 760 cm.

[@hAnumAndAsAm]

If u place a suction pump around barometer , height of the Mercury falls because the suction decreases the number of air molecules around so there by decreasing their weight over the Mercury surface in through which is the atmospheric pressure. This is what happens at altitudes. At higher altitudes , there are less number of molecules in a given volume i.e, less denser air.

[@sunildagia]

There is a correction in your question it is not 760cm it is 76 cm

[@lozinajaved979]

why we use mercury here not any other element to measure atmospheric pressure?

[@aiyshahussein6169]

Lozina Javed because mercury is denser and don't evaporate easily

[@umeshsingh9747]

as ot is the only metal which is in liquid form and has a reasons ke size for the height of coloumn

[@kainaatabbas9196]

Let's suppose we are taking water instead of mercury we have to take a very long tube of about 10m long because mercury is 13.6 times more dense than water

[@tqaquotes9379]

09:36 weight of column of mercury
