Try this class experiment to investigate how much energy different foods contain. In this practical, students burn a sample of a foodstuff of known mass, heating a known volume of water. From the measured temperature change, students calculate the energy transferred to the water, and hence estimate the energy present per unit mass of food.

22 sie 2023 · There are two ways to estimate the amount of energy in food and drinks. The first is called “bomb calorimetry”. This gold-standard method involves placing a small sample of food or drink inside a device known as a bomb calorimeter. The food is burned in the presence of oxygen, releasing heat.
14 paź 2022 · A machine called a calorimeter can measure the energy in food. (Image credit: Getty) This tool directly measures the amount of energy that a food contains, said Ruth MacDonald, professor and...
Calculate the energy released by this food type using this equation: Energy released (J) = mass of water (g) x rise in temperature (°C) x 4.2. Repeat steps 1-8 with...
In this project you will learn a method for measuring how much chemical energy is stored in different types of food and express your result in Calories (note the capital "C"), as this is the unit of energy widely used to quantify food energy.
