4. Lab Overview kExplanation about why you would like to test the 4 foods kUse Calorimetry Protocol kPredict results kCreate a data table or results kConduct test kExplanation about why you would like to test the 4 foods kUse Calorimetry Protocol kPredict results kCreate a data table or results kConduct test

5. Background information kOpen your book to page 295 and read the beginning of the Calorimetry Protocol

6. Logic kSuppose you drink a energy drink that contains 160 Calories, what does that mean as far as the amount of energy it contains?

7. k1 calorie raises 1 ml 1 degree C k1 kcalorie (Calorie) is 1,000 calories k1kcal raises 1 Liter 1 degree C kRoom temp= 20 degrees C kBoiling = 100 degrees C k 80 kcal raises 1 liter 80 degrees C kTherefore, 160 kcal would raise 2 liters 80 degrees C, or there is enough energy in one energy can to boil 2 liters of water k1 calorie raises 1 ml 1 degree C k1 kcalorie (Calorie) is 1,000 calories k1kcal raises 1 Liter 1 degree C kRoom temp= 20 degrees C kBoiling = 100 degrees C k 80 kcal raises 1 liter 80 degrees C kTherefore, 160 kcal would raise 2 liters 80 degrees C, or there is enough energy in one energy can to boil 2 liters of water

Procedure 1.Select foods(4) per table 2.**Predict which has the highest calorie 3.Measure mass of food (equal) 4.Go to calorimeter set-up 5.**Add 50ml of water to flask 6.**Suspend thermometer in water and measure initial temperature 7.Place food in wire holder and inside can. **Record initial mass 1.Select foods(4) per table 2.**Predict which has the highest calorie 3.Measure mass of food (equal) 4.Go to calorimeter set-up 5.**Add 50ml of water to flask 6.**Suspend thermometer in water and measure initial temperature 7.Place food in wire holder and inside can. **Record initial mass

10. Procedure cont. 8. Ignite food sample 9.Place flask on top of can and begin measuring temperature 10. **Record maximum temperature 11. **Measure mass of burned food and wire holder 12. ##Repeat procedure for 2 other foods and record results. 13. Analyze your data 8. Ignite food sample 9.Place flask on top of can and begin measuring temperature 10. **Record maximum temperature 11. **Measure mass of burned food and wire holder 12. ##Repeat procedure for 2 other foods and record results. 13. Analyze your data

11. Analyzing data kDetermine change in temperature. kChange in temperature= High temp - low temp. kDetermine change in temperature. kChange in temperature= High temp - low temp.

12. Analyzing data kCalculate number of calories produced per food. kCalories produced= change in temperature X 50 kCalculate number of calories produced per food. kCalories produced= change in temperature X 50

13. Analyzing data kCalculate calories per gram of food. kCalories per gram of food = calories produced ÷ grams of food burned kKilocalories=calories / 1000 kCalculate calories per gram of food. kCalories per gram of food = calories produced ÷ grams of food burned kKilocalories=calories / 1000
