If one newton force is applied to unit crossesctional area (in $m^2$)  of any subject then the amount of pressure applied is

The amount by which the pressure measured in a fluid exceeds that of the atmosphere is known as 

One atmospheric pressure at sea level is equal to 760 cm of Hg.

A bubble is at the bottom of a lake of depth $h$. As the bubble comes to the sea level, its radius increase three times. If atmospheric pressure is equal to $l$ metre of a water column, then $h$ is equal to

If a given mass of gas occupies a volume of 10 cc at 1 atmospheric pressure and a temperature of ${ 100 }^{ 0 }$C (373.15 k). What will be its volume at 4 atmospheric pressure; the temperature being the same 

A narrow glass tube, $80$ cm long and opens at both ends, is half immersed in mercury, now the top of the tube is closed and is taken out of mercury A column of mercury $20$ cm long remains in the tube. Find the atmospheric pressure

Find pressure on swimmer at a depth of $10 m$ in water

A brass scale, correct at $0^\circ C$, registers the height of a mercury barometer at 76.5 cm at $30^\circ c$. What is the actual height of the barometer? [Linear expansivity for brass=$1.9\times10^{-5} K^{-1}$]

A barometer is carried from the $1^{st}$ floor to the $20^{th}$ floor of a building. Why does the reading on the barometer fall?

Atmospheric pressure can be measured by which of the following instruments
