On a separate sheet of paper, type (double-spaced, 11-12 point font, and correct use of subscripts and degree signs) a well-supported, convincing conclusion paragraph (labeled either Task 1 Conclusion or Task 2 Conclusion that identifies the unknown for each task. If you need further information about writing conclusions, please refer to the lab. "Drawing Conclusions," completed earlier this term. 2. Submit a single PDF file containing assignment sheets, calculations, and both conclusions in the Moodle Assignment drop box by the deadline. Make sure the pages are in the correct order with the correct orientation Task 1: Use the experimentally determined average specific heat and average density that wa emailed to you to identify the unknown metal from the list of possible unknowns. Note: Since specific heats have more experimental uncertainty, you may need to increase your range from +5% to 10% (or slightly higher) when deciding which specific heats to include.
