Follow the steps above to solve the problem: a diamond is underwater; a light ray enters one face of the diamond, then travels at an angle of 30 degrees with respect to the normal. what was the ray's angle of incidence on the diamond? the index of refraction of water is nwater=1.33, and the index of refraction of diamond is ndiamond=2.42.

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.
