  5. 1. Given temperatures in degrees Fahrenheit, Celsius, or Kelvin, use the appropriate formula to
  6. convert to one of the other temperature units.
  7.  
  8. a. Celsius to Fahrenheit,
  9. you multiply the Celsius amount by 1.8 then add 32 to make it Fahrenheit
  10.  
  11. b. Fahrenheit to Celsius F = (9/5)C + 32
  12. c. Celsius to Kelvin
  13. d. Kelvin to Celsius C = (5/9)(F – 32)
  14. e. Fahrenheit to Kelvin
  15. f. Kelvin to Fahrenheit K = C + 273.15
  16.  
  17. 2. Given quantities of energy in Calories, calories, or joules, use the appropriate formula to
  18. convert to one of the other energy units.
  19.  
  20. a. calories to Calories
  21. b. Calories to calories 1 cal = 4.184 J
  22. c. Joules to calories
  23. d. calories to Joules 1 Cal = 1000 cal (note difference)
  24.  
  25. 3. Given a Table of Specific Heats, compare the specific heats of substances to determine which
  26. substance takes the least or most energy to heat up.
  27. Delta(T)=T-T
  28. 4. Given m, c, Ti and Tf, use the formula, q = mcT, to calculate the amount of heat, q, consumed
  29. or produced.
  30.  
  31. 5. Given q, m, and c, use the formula, q = mcT, to calculate the initial or final temperature, Ti
  32. or Tf
  33. 6. Given q, m, Ti and Tf, use the formula, q = mcT, to calculate the specific heat capacity, c.
  34.  
  35. 7. Given q, c, Ti and Tf, use the formula, q = mcT, to calculate the mass of an object, m.
  36.  
  37. 8. Given raw calorimetry data, use the formula, q = mcT, to calculate the specific heat capacity of
  38. an unknown substance. (2.8) (2.9) (2.10) (P9) (P10)
