How does a calorimeter measure calorie content?
Q: I have heard of a calorimeter. Apparently it is an instrument used to measure calorie content. How does one work? Can you just go buy one of these things? What about when the news goes to check out diet restaurants to see if the food has the calories that the restaurant claims it does, what do they use?
A: Ok, here is the gobbledeegook science stuff. No you cannot do it at home unless you are a physicist!Physicists measure the energy content of food by burning the food. To a physicist, a calorie is the heat flow needed to raise the temperature of one gram of water by one degree Celsius. To measure the calorie content of food accurately, scientists use a “bomb calorimeter”. The food sample to be measured is dried and ground into a powder (important point – all water content eliminated). Then it is placed into the bomb calorimeter, a strong metal container surrounded by a water bath. The metal container is pumped full of pure oxygen at 30 atmospheres pressure and the food is ignited. The resulting energy release is fast and violent, just like a bomb. The steel container holds in the explosion. Pure oxygen promotes combustion, and high-pressure oxygen greatly enhances combustion. All of the burnable parts of the dried and powdered food will burn in a calorimeter, leaving just a touch of ash. The calorimeter turns the energy stored in the food into heat flow. The temperature increase of the water and metal of the calorimeter reveals how many calories the food contained.
How can I measure my calorie intake with my calorie burn?
Q: I’m trying to burn fat and I am running a lot, and eating not a lot because Im just trying to eat less than I burn but I dont know how much I can eat.
