Question

A single serving can of Campbell's Pork & Beans contains 9.0 g of protein, 43 g of carbohydrates, and 3.0 g of fat. Proteins and carbohydrates each contain 4.0 Calgand fats contain 9.0 Callg. Calculate the total Calorie content of the beans. Protein 9.ogx 4.0 call = 36g/cal Carb: 43 g x 4.0cal 18=1728lcal Fat 3. og X 9.00lig = gigkel 235lcal The contents of the above can of beans were burned to release the chemical energy stored in the food. The energy was used to heat 10.0 kg of water at an initial temperature of 25.0 °C. After the beans were burned, what was the temperature of the water?

Answer 1

proteins 9.ug. carbohydrater - ug. Pats - 3.0g. Energy from components proteins = (9.ogx 4.0 calon) & 36.0 cal Carbohydrates - 3 g x 4.0 calgn) = 172 cab Eat = (3.0g x 9.0 calg & 27. 0 cob Total colorie = (2700 + 172 + 36.0) cal . = 235 cal Now I cal = 2. 235 cal = = 4.184 T. (235 x 4. 184 T 483.24 J is its used to temperature This amount of energy heat water and raise q = cp. m.
