four children are playing tug-of-war. the two
children on the right pull with forces of magnitude
84 n and 86 n, and one of the children on the left
is able to pull with a force of magnitude 83 n. if the
rope remains stationary, how hard is the second child
on the left pulling?

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.
