A 0.15 m3 container is filled with 0.1kg of air. The pressure of the container is lower than its ambient pressure and it develops a hole so that air leaks into the container at a constant mass flow rate of 0.002 kg/s. The air can be modeled as an ideal gas. Determine the mass, in kg and pressure, in kPa in the container after 20 seconds if the temperature is 20 degree C.
