Calculate the minimum pressure required to compress 500 ml of air at 1 atm to 300 mL at the same temperature.

The gases which obey Gas Laws at all temperatures and pressures are called ideal gases. Calculate the minimum pressure required to compress 500mL of air at 1 atm to 300mL at the same temperature.

A gas occupies a volume of '250 m L' at '700 mm' of 'Hg' at '25^circ C'. What is the additional pressure required to reduce the gas volume to '200 mL' at the same temperature?

What will be the pressure of the gaseous mixture when '0.5 ~L' of 'H_2' at '0.8' bar and '2.0' L of dioxygen at '0.7' bar are introduced in a '1 L' vessel at '27^circ C' ?

The air column in a pipe closed at one end is made to vibrate in its second overtone by a tuning fork of frequency 440 Hz. The speed of sound in air is 330 ms^(-1) . End corrections may be neglected. Let p_(0) denote the mean pressure at any point in the pipe and Deltap_(0) the maximum amplitude of pressure variation. (a) Find the length L of the air column. (b) What is the amplitude of pressure variation at the middle of the column? (c ) What are the maximum and minimum pressures at the open end of the pipe? (d) What are the maximum and minimum pressures at the closed end of the pipe?

What will be pressure exerted by a mixture of '3.2 g' of methane and '4.4 g' of carbon dioxide contained in a '9 dm^3' flask at '27^circ C' ?

Calculate the pressure exerted by one mole of CO_(2) gas at 50^(@)C , confined to a volume of 0.125 dm^(3) , using the law of corresponding states, given that the critical constants of the gas are V_(m, c)= 0.0957 dm^(3), T_(c )= 304K" and "P_(c )= 73.0 atm .

One litre flask contain air, water vapour and a small amount of liquid water at a pressure of 200 mm Hg. If this is connected to another 1L evacuated flask, what will be the final pressure of the gas mixture at equilibrium? Assume the temperature to be 50^(@)C. Aqueous tension at 50^(@)C = 93 mm of Hg
