Consider a piston-cylinder assembly in which air expands adiabatically from an initial state where pi= 100 lbf/in, u = 3.704 f/ib, and t = 1000°r, to a final state where p2 30 lb/in". the process is polytronic with n=1.4. the change in specific internal energy (in turib), can be expressed in terms of temperature change as au - (0.171)(12 - 11). determine the final temperature in "r). neglect kinetic and potential energy effects.

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.
