- 1. Given temperatures in degrees Fahrenheit, Celsius, or Kelvin, use the appropriate formula to
- convert to one of the other temperature units.
- a. Celsius to Fahrenheit,
- you multiply the Celsius amount by 1.8 then add 32 to make it Fahrenheit
- b. Fahrenheit to Celsius F = (9/5)C + 32
- c. Celsius to Kelvin
- d. Kelvin to Celsius C = (5/9)(F – 32)
- e. Fahrenheit to Kelvin
- f. Kelvin to Fahrenheit K = C + 273.15
- 2. Given quantities of energy in Calories, calories, or joules, use the appropriate formula to
- convert to one of the other energy units.
- a. calories to Calories
- b. Calories to calories 1 cal = 4.184 J
- c. Joules to calories
- d. calories to Joules 1 Cal = 1000 cal (note difference)
- 3. Given a Table of Specific Heats, compare the specific heats of substances to determine which
- substance takes the least or most energy to heat up.
- Delta(T)=T-T
- 4. Given m, c, Ti and Tf, use the formula, q = mcT, to calculate the amount of heat, q, consumed
- or produced.
- 5. Given q, m, and c, use the formula, q = mcT, to calculate the initial or final temperature, Ti
- or Tf
- 6. Given q, m, Ti and Tf, use the formula, q = mcT, to calculate the specific heat capacity, c.
- 7. Given q, c, Ti and Tf, use the formula, q = mcT, to calculate the mass of an object, m.
- 8. Given raw calorimetry data, use the formula, q = mcT, to calculate the specific heat capacity of
- an unknown substance. (2.8) (2.9) (2.10) (P9) (P10)
