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

A certain volume of dry air at 20^(@)C is expanded to there times its volume (i) slowly, (ii) suddenly. Calculate the final pressure and temperature in eachh case. Atmospheric pressure =10^(5)Nm^(-2), gamma of air =1.4

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

Define (i) atmospheric pressure (ii) one atmosphere.

The velocity of sound in air is affected by change in the (i) atmospheric pressure (ii) moisture content of air (iii) temperature of air (iv) composition of air.
