Answer the following : Explain with a neat diagram , how is atmospheric pressure created . Does it depend on height above sea level ?

What happens when a pressure greater than the atmospheric pressure is applied to pure water or a solution?

If a given mass of gas occupies a volume 60 m^3 one atmospheric pressure and temperature of 100^@C , what will be its volume at 4 atmospheric pressure when temperature remains same?

The molecules of a given mass of a gas have root mean square speeds of 100 m s ^(-1) at 27^@C and 1.00 atmospheric pressure . What will be the root mean square speeds of the molecules of the gas at 127^@C and 2.0 atmospheric pressure ?

300 cc of a gas is compressed to 150 cc at the atmospheric pressure of 10^6 dyne/ cm^2 . If the change is sudden, what is final pressure ? [Given gamma=1.4 ]

1mm^3 of a gas is compressed at 1 atmospheric pressure and temperature 27^@C to 627^@C . What is the final pressure under adiabatic condition (gamma for the gas =1.5 )

A bubble of a gas released at the bottom of a lake increases to eight times its original volume when it reaches the surface. Assuming that atmospheric pressure is equivalent to the pressure exerted by a column of water 10m height, the depth of the lake is "____________" .

What is the Henry's law constant of dissolved O_(2) at 10^@C at 1 atmospheric pressure , if partial pressure of oxygen is 0.24 atm ? the concentration of dissolved oxygen is 3.12xx10^(-4) mol dm ^(-3)
