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 °C.
