February Assignments--IB Physics 1

Monday, Feb. 2

Pre-lab: Calorimetry basics
time to begin working on the WebAssign due Friday

HW: look up (preferably from your textbook) the specific heat capacity for aluminum
HW: Due Friday: WA thermal #2: Specific Heat
note: for ALL the problems in this set for which you are not initially provided the specific heat capacities, you must use the values found in your textbook (or notes) in table 11.1. if you do not use the proper values for the specific heat capacity, there's a good chance that you'll get an answer that is just outside the tolerance range for WebAssign's answer key.

HW: Due Monday: A.S. 3.1.1 - 3.1.7

Tuesday, Feb. 3

Lab: Calorimetry
done fully in your lab notebook. Lab analysis is fully due on Thursday at the beginning of class. You are expected to write in ink (blue or black is preferred--please do not use green or purple or a color that is hard to read for anyone but you) and you are expected to write legibly. You will not be typing up any part of this lab.

Your lab will include:
- Data table (using the units given in class yesterday)
- Uncertainties for each measured value
- Complete, thorough, clearly worked-out calculation for determining the specific heat capacity for your metal sample.
- complete, thorough, clearly worked-out calculation for determining the uncertainty in your experimental value for the specific heat capacity of your metal sample
- the final answer of specific heat +/- uncertainty, written to the correct sig. figs and with the correct units.
- a sentence to state the identification of the material that most closely matches your calculated specific heat value.
- a sentence to state the actual identification and the accepted specific heat value for the metal you actually have
- a percent difference calculation and a brief discussion of your own value's accuracy.
- a brief discussion of the accuracy and precision of your value based on the uncertainty that you calculated.
