An open vessel at `27^(@)C` contains 28 grams of `H_(2)` .Its temperature increases upto `127^(@)C` .What fraction of moles of `H_(2)` gas escapes out of vessel?

An ideal gas is present in an open vessel at 27^(@)C . If this gas is heated upto TK temperature so that (2)/(3) of final moles of gas are escaped out, then calculate final temperature T.

An open vessel containing air is heated from 27^(@)C to 127^(@)C . The fraction of air originally present which goes out of it is

A gas is filled a container at 27^(@)C . On increasing the temperature to 127^(@)C , 1 litre (having (1)/(4) th mass) of the gas escape out of the container. Calculate the volume of the container.

A gas is filled in a container at 27^@ C . On increasing the temperature to 127^@ C , 1 litre (having (1)/(4) th mass) of the gas escape out of the container. Calculate the volume of the container.

A gas cylinder contains 320 gm of O_(2) at 30 atm and 27^(@)C what mass (in gram) of O_(2) would escape if first the cylinder is heated to 127^(@)C and then valve is held open until the pressure the cylinder become 1 atm ( the temperature being maintained at 127^(@)C ).

A gas is filled in a container of volume V at 121^(@)C . To what temperature should it be heated in order that (1)/(4) th of the gas may escape out of the vessel?

A gas is filled in a container of volume V at 121^@ C . To what temperature should it be heated in order that (1)/(4) th of the gas may escape out of the vessel?

A vessel contains 1 mole of O_2 at a temperature T. The pressure of gas is P. An identical vessel containing 1 mole of the gas at a temperature 2T has pressure of -

A2 litre vessel is filled with air at 50^(@)C and pressure of 3 atm. The temperature is now raised to 200^(@)C A valve is now opened so that the pressure inside drops to one atm What fraction of the total number of moles, inside escaped on openig the valve ? Assume no change in the volume of the container .
