  1. Solve Kcal review problems:

  2. 1. Find the # of kcals in this food • 27 grams of carbs • 10 grams of fat • 4 grams of protein • Answer: • 27 x 4 =108 kcals • 10 x 9 = 90 kcals • 4 x 4 = 16 kcals • 214 kcals

  3. 2. Find the amount of kcals for carbs & lipids • 5 grams of fat • 11 grams of protein • 33 grams of carbs • Answer: • 9 x 5 = 45 kcals • 33 x 4 = 132 kcals • 177 kcals

  4. 3. Find the amount of kcals • Starting temp is 770C • Ending temp is 2480C • Answer: • T =T2-T1 • T =248-77 • T = 1710C • T x V = calories • V = 10ml • 171 x 10 = 1,710 • 1,710/1,000= • 1.710

  5. 4. Find the change in temperature • Starting temperature is 450C • Ending temperature is 3130C • T =T2-T1 • 313 – 45 = • 2680C

  6. 5. Find the amount of fat kcals in this product • 39 grams of carbohydrates • 12 grams of fat • 13 grams of protein • 12g x 9 kcals/g = • 108 kcals

  7. 6. Find the amount of calories • Starting temp is 800C • Ending temp is 3300C • Answer: • T =T2-T1 • T =330 - 80 • T = 2500C • T x V = calories • V = 10ml • 250 x 10 = • 2,500

  8. 7. If a food has 7g of carbs, 4g of protein and 3g of fat. How many kcals are in this food? • 7g x 4 kcal/g = 28 kcals • 4g x 4 kcal/g = 16 kcals • 3g x 9 kcal/g = 27 kcals • 71 kcals

  9. 8.When I burn the food the water temperature raises from 70C to 175º C. What is the T? • T = T2 – T1 • 175º C - 70C = T • T = 105 ºC

  10. 9.Using your T from the previous problem calculate the calories if you used 10mL of water. • T x V = calories • 105 ºC x 10mL = calories • 1050 calories

  11. 10.Calculate your T and your amount of calories. The water temperature raises from 65 ºC to 185 ºC using 10mL of water. • T = T2 – T1 • T = 185 ºC - 65 ºC • T = 120 ºC • T x V = • 120 x 10 = 1,200

  12. 11.Find the kcals of each nutrient. 71g of carbs, 10g of fat and 5g of protein. • 71g x 4 kcal/g =284 kcals of carbs • 10g x 9 kcal/g = 90 kcals of fat • 5g x 4 kcal/g = 20 kcals of protein

  13. 12. If you eat a product that contains 23g of carbs, 4g of protein, & 5g of lipids. How many total Calories will you consume? • 23g x 4 kcal/g =92 kcals of carbs • 4g x 4 kcal/g = 16 kcals of protein • 5g x 9 kcal/g = 45 kcals of fat • Total = 153 kcals

  14. 13.If you eat a product that has 4g of fat, 7g of protein & 20g of carbs, how many total Calories will you get from carbs & protein? • 20g x 4 kcal/g =80 kcals of carbs • 7g x 4 kcal/g = 28 kcals of protein • Carbs + protein = 108kcals

  15. 14. If I started out with a temperature of water of 35˚C and the ending temperature is 54˚C what is my ΔT? Find my total amount of calories if my volume is 30ml. • Starting temp is 350C • Ending temp is 540C • Answer: • T =T2-T1 • T =54-35 • T = 190C • T x V = calories • V = 30ml • 19 x 30 = 570 calories • 570/1,000=.57 Kcals

  16. 15. If I start out with a temperature of 45˚C and end with a temperature of 55˚C what is my change in temperature? • Starting temp is 450C • Ending temp is 550C • Answer: • T =T2-T1 • T =55-45 • T = 100C
