A potential difference of 25.0 V is applied between the ends of a 30.0-m gold wire with a
diameter of 5.50 mm. The resistivity of the wire is 2.44 × 10−8 Ω.m., Calculate
the drift speed of the electron in the wire. Assume one atom conducts one electron.
(molar mass of gold =196.97 g/mol and ρgold = 19.32 g/cm3

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.
