Gas Cylinder

One of the limbs of a mercury manometer is connected to a gas cylinder. The mercury level in the limb connected to the gas cylinder is 10 cm higher than that in the other limb. Then the gauge pressure of the gas is _______ cm of Hg.

The compressibility factor for a given real gas is 0.927 at 273 K and 100 atm Calculate the amount of gas required to fill a gas cylinder of 100 litre capacity under given conditions (Mol weight of gas =30) .

A gas cylinder has walls that can bear a maximum pressure of 1.0xx10^(6) Pa. It contains a gas at 8.0xx10^(5) Pa and 300K. The cylinder is steadily heated. Neglecting any change in the volume calculate the temperature at which the cylinder will break.

A gas cylinder has walls that can bear a maximum pressure of 1.0times10^(6)Pa .It contains a gas at 8.0times10^(5)Pa and 300K .The cylinder is steadily heated.Neglecting any change in the volume.If the temperature at which the cylinder will breaks is 75nK find n .?

A gas cylinder contains 370 g oxygen at 30.0 atm pressure and 25^(@)C . What mass of oxygen will escape if the cylinder is first heated to 75^(@)C and then the valve is held open until gas pressure becomes 1.0 atm , the temperature being maintained at 75^(@)C ?
