Activity #1 1. Reset the system and make sure the Constant Parameter button is set to None. 2. Pump 50 heavy gasmolecules and 50 light gasmolecules in the gascontainer. How do the velocities of the heavy gasmolecules compare to those of the light gasmolecules? 3. Use the Heat Control to add energy. Notice that the thermometer shows an increasing temperature. What happens to the velocities of the gasmolecules? 4. Use the Heat Control to remove energy. What happens to the velocities of the gasmolecules?
