1. PHSC 102-------Please read along in your text book Hewitt, as we cover material in chapters 23, 24 and 25.

2. CLAB 123------- Please be prepared for experiment 5.You should read the introductory material and the procedure in your lab manual (or modification if applicable). Be sure to prepare an outline (summary) of the procedure in your notebook. Remember to bring your lab manual and notebook to class and wear proper lab attire. Please also bring a calculator (does not need to be scientific). Please study the link on the class web page for Common Laboratory Operations and Apparatus.

Your lab reports for experiment 4 will be due. Please read Part II of the Information Sheet before starting the report. Remember that all calculations are to include units and are to be to the proper number of significant digits. Multiple pages must be stapled.

Experiment 4 instructions.

Instructions are linked on the Information Sheet.

Experiment 5 instructions.

I. Raw Data- Make a table with masses, temperatures for runs 1 and 2. Give a description of the metal (color, density, hardness) and do not forget your unknown letter.
II. Sample Calcs.- Show all calculations for one run.  Use the equations that I placed on the board.
III. Results- Table with specific heat and molar mass for each run.
IV. Discussion- Indicate and discuss the identity of your metal (why do you think it is the metal you have selected).
