Click on the "Gas Properties Simulation" link to perform simulations in the setup satisfying the given conditions. With no constant parameters selected and initially at 0 K with no heat control (heat control=0) , pump some heavy species gas into the container. 1. Explain how the gas particles flow/move into the empty container once the gas enters the container? Afterward a while, what direction does the particles move? 2. What happens to the temperature soon after the gas particles enter the container? 3. What happens to the pressure when the gas particles enter the container? 4. Next, pump some additional heavy species gas particles into the container. What happens to the pressure
