Express standard atmospheric pressure in (i) `Nm^(-2)` (ii) bars and (iii) torr.

The standard atmosphere pressure is

Define standard atmospheric pressure.

Derive an expression for atmospheric pressure.

Express 1 atm pressure into N//m^(2) and bar.

What will be the normal atmospheric pressure in bar and also in torr ?

Calculate the pressure caused by gravitational copmression at the centre of the earth . Express the result in terms of standard atmospheric pressure .Mass of the earth = 6.0 xx 10^(24) kg , radius of the earth = 6.4 xx 10^(6) m and g ( at the surface of the earth ) =9.8 m s^(-2) . 1 standard atmospheric pressure = 10^(5) Nm^(-2) .

In Boyle's law calculations, the pressure of the gas or applied pressure should be expressed in (i) pascal ,(ii) atmosphere (iii) bar ,(iv) torr

Write the value of : Standard pressure in (i)atm (ii)mm Hg (iii)cm Hg (iv) torr
