It is measured in food calories or kilocalories, (kcal)
A kilocalorie = 1000 calories of heat.
A bomb calorimeter is used to determine the heat content of foodstuffs.
A representative sample of food is collected and 1 gram is placed in the calorimeter, the bomb is then filled with oxygen and placed in a vessel holding a measured amount of water. The sample is then burned in the bomb and the heat transferred to the water is measured, giving the total amount of heat released, in calories. This is then divided by 1000 to get food calories or kcals.
What else can I help you with?
If a scientist wanted to track beta decay she would need an instrument that could measure?
energy release
Atoms can absorb energy in their orbital electrons and release it as light scientist use a what to measure the light in order to what?
spectroscope.....find out what kind of atoms are giving off light energy
How does a scientist describe energy?
Scientist describe energy as ability to do or perform work.
What do scientist use to measure the energy content of foods?
Scientists use a tool called a bomb calorimeter to measure the energy content of foods. This device burns a sample of the food in a controlled environment and calculates the amount of heat produced, which is used to determine the energy content in the form of calories.
