Problem

- A perfectly conducting vessel of volume

V = 0.4 \text{ m}^3

contains an ideal gas at constant temperature

T = 273 \text{ K}

. A portion of the gas is let out and the pressure of the gas falls by

\Delta p = 0.24 \text{ atm}

. (Density of the gas at STP is

\rho = 1.2 \text{ kg/m}^3

). Find the mass of the gas which escapes from the vessel.
