An insulated `0.2 m^(3)` tank contains helium at `1200 kPa` and `47^(@)C`. A value is now opened, allowing some helium to escaped. The valve is closed when one-half of the initial mass has escped. The temperature of the gas is `(root(3)(4) =16)`

An insulated 0.2 m^(3) tank contains helium at 1200 kPa and 47^(@)C . A valve is now opened, allowing some helium to escaped. The valve is closed when one-half of the initial mass has escaped. The temperature of the gas is (root(3)(4) =16)

A piston cylinder device initially contains 0.2m^(3) neon (assume ideal ) at 200kPa inside at T_(1) ""^(@)C . A valve is now opened and neon is allowed to escape until the volume reduces to half the initial volume. At the same time heat transfer with outside at T_(2) ""^(@)C ensures a constant temperature inside. Select correct statement(s) for given process

A tank used for filling helium balloons has a volume of 0 .3 m^3 and contains (2.0) mol of helium gas at 20 .0^@ C . Assuming that the helium behaves like an ideal gas. (a) What is the total translational kinetic energy of the molecules of the gas ? (b) What is the average kinetic energy per molecule ?

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 .
