A vessel A of volume 5 litre has a gas at pressure of 80 cm column of Hg. This is joined to another evacuated vessel B of volume 3 litre. If now the stopcock S is opened and the apprature is maintained at constant temperature then the common pressure will become -

A bulb of unknown volume 'V' Contains an ideal gas at 2 atm pressure. It was connected to another evacuated bulb of volume 0.5 litre through a stopcock. When the stopcock was opened the pressure in each bulb became 0.5 atm. Then V is

A vessel containing 5 litres of a gas at 0.8 m pressure is connected to an evacuated vessel of volume 3 litres. The resultant pressure inside with be (assuming whole system to be isolated)

The pressure of a gas in a vessel is 80 cm of Hg. Now 25% of the same gas is also introduced into the same vessel. If the process is done at the same temperature, find the final pressure of the gas.

A gas is enclosed in a vessel of volume V at temperature T_(1) and P, the vessel is connected to another vessel of volume V//2 by a tube and a stopcock. The second vessel is initially evacuated. If the stopcock is opened, the temperature of second vessel becomes T_(2) . The first vessel is maintained at a temperature T_(1) . What is the final pressure P_(1) in the apparatus ?
