Aperfect gas is contained in a cylinder of fixed volume and is separated into two sections a and b by a frictionless piston; no heat can pass ugh the piston. section b is maintained at a constant temperature of 300k; that is, all changes in section b are isothermal. there are 2.00 mol of gas molecules in each section and the constant-volume heat capacity of the gas is 20]k mol", which can be assumed to be constant. initially t v, m - t, 300 k, v v 2.00 dm3. energy is then supplied as heat to section a so that the gas in a expands, pushing the piston out and thereby compressing

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.
