What will be the minimum pressure required to compress 500 `dm^3` of air at 1 Bar to 200 `dm^3` at 30°C ?

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' ?

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' ?

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
