To run the simulation, you will alter mass in creating momentum of the carts. The total mass of the carts in the
collision is the
variable.
The velocity of the combined carts after the collision will change because of the change in the independent variable.
In this way, the final velocity is the
variable.

4. now look at the green lines you created by connecting the three boiling point data points and the three melting point data points. for each of these lines, describe any trends you see. 5. locate the elements on your periodic table that you circled in green on your graph. what term or description would you use to identify these elements with respect to the periodic table? 7. using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers.
