RPS/HPS Calculating Change in Thermal Energy

In Class:

• Calculating Change in Thermal Energy
• Understanding Specific Heat Capacity
• Lecture notes available here.
  

Homework:

• Verify/correct textbook p. 148 #14. This was done in class when Mr. Yamashita was out, and was handed back in class today. However, it was not corrected by Mr. Yamashita (he just checked that it was done... credit was given if it was done, not on the veracity of the answer).
• Answers to Textbook p. 148 Questions 1-10, 13, 14, & 18
  

Videos:
In the videos, the values I use for the specific heat capacities of water and aluminum are incorrect. The actual values are 920 J/kg*C for Aluminum and 4184 J/kg*C for water. The values I used are so different because the units I used in my lecture are different from the normal SI units for specific heat capacity. (and the value I was remembering for Aluminum is actually the value for graphite)
