2. 1. 1 Calorie = ____ calorie(s)

3. 2. The specific heat capacity of water is_______.

4. 3. k is the symbol that represents this number.

5. 4. What is the scientific way to express the number 1,000?

6. 5. 1 calorie = ______ J

7. 6. The symbol J represents this measurement of heat.

8. 7. Write one of the two equations we used to determine the amount of Heat Energy in a substance.

9. 8. Compare the reactions of cellular respiration and combustion, in reference to amount of required energy to complete both.

10. 9. What problem could there be with measuring the complete energy of a 10 lb. Cheeto in the lab that we performed in class?

11. 10. If a food source contains 3200 J of energy; It’s mass is 3.4 kg; What would the change in temperature of water in the calorimeter have been?

12. 11. How heavy is a piece of caramel popcorn if it was burned in our lab and found to raise the temperature of water from 32°C to 54 °C ? 7.5 kJ was recorded in the data.

13. 12. While constructing this “Learning Opportunity”, I used up.65 moles of Adenosine Triphosphate. How many calories did I burn? Show the matrix work!!!

14. BONUS Name an example from each category. Monosaccharide→ Disaccharide → Polysaccharide → Label which belongs to each.

15. ANSWERS

16. 1. 1,000 2. 4.2J / g °C 3. 1,000 4. 1x10 3 5. 4.2 J 6. Joules 7. q = MC∆T or J = g * S.H. * ∆T

17. 8. Cellular Respiration requires less energy to start reacting. More efficient method. 9. H 2 0 could evaporate. q/(M*C) = ∆T 3200J/(3400g*4.2J/g°C) = ∆T =.22°C

18. 11. q=MC ∆T…..q/C ∆T = M 7500J/(4.2J/g°C)*(22°C) = M = 81.17g 12. (.65 mol ATP) * (7.3Calories/1mol ATP) = 4.75 Calories

19. BONUS Monosaccharide → Disaccharide → Poly saccharide→
