The drawing shows a device that you can make with a piece of cardboard, which can be used to measure a person's reaction time. hold the card at the top and suddenly drop it. ask a friend to try to catch the card between his or her thumb and index finger. initially, your friend's fingers must be level with the asterisks at the bottom. by noting where your friend catches the card, you can determine his or her reaction time in milliseconds (ms). calculate the distances (a) d1, (b) d2, and (c) d3.

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.
