What is calorimetry used for?
To measure the energy content of food.
What type of machine do food scientists use to measure energy content?
Calorimeters.
What type of food is best for burning in calorimetry experiments?
Dried food, such as dried beans or pasta.
How is the food prepared for a calorimetry experiment?
Weigh a small amount and skewer it on a mounted needle.
What is the purpose of adding water to a boiling tube in a calorimetry experiment?
To measure the amount of energy transferred when the food is burnt.
How do you calculate the energy in food?
Energy in food (J) = Mass of water (g) x Temperature change of water (°C) x 4.2.
How is the energy per gram of food calculated?
Energy per gram (J/g) = Energy in food (J) / Mass of food (g).
Why should the Bunsen burner not be near the water during the experiment?
To prevent affecting the temperature results of the water.
