Sentences with phrase «bomb calorimeter»

A bomb calorimeter is a device used to measure the amount of energy in a substance, like food or fuel. It does this by burning the substance in a controlled environment and measuring the heat produced. It helps scientists understand the energy content of different materials. Full definition
ICE's are far from bomb calorimeters and depend heavily as well on combustion speed as well.
By 1889, Rubner had built a remarkably accurate bomb calorimeter which lead to many of his findings, most notably: the thermic effect of protein, the energy laws of physics applying to caloric balance, and his most fundamental finding that a calorie is a calorie.
It was also around this time scientists began to develop bomb calorimeters to measure the energy value of food.
Do we have an internal bomb calorimeter to measure calories and change behavior / metabolism based on calories?
Traditionally, scientists calculated the energy content of foods using a large piece of machinery called a bomb calorimeter.
The original method used to determine the number of kcals in a given food directly measured the energy it produced.The food was placed in a sealed container surrounded by water — an apparatus known as a bomb calorimeter.
Baer's team took a gram of it and put it into a device known as a bomb calorimeter (Kal - oh - RIM - eh - tur).
Android you is a machine, like a bomb calorimeter, and the number of calories your mechanical twin consumes will equal the number of calories it burns.
Rubner also noted that unlike the bomb calorimeter, the human body wasn't able to metabolise nitrogen from protein, and these calories were excreted through urine.
If you were to put all of this food in a bomb calorimeter, burn it, and measure the heat that came off — you'd find the «gross energy» of your entire menu.1
The body is more than a bomb calorimeter, it is dynamic and responds to signals and can change the masses of different «compartments» in accordance with the signals.
The body is not simply a bomb calorimeter, nor is it an isolated system.
The CICO model essentially treats the body as a bomb calorimeter and an isolated system immune to perturbations.
That's a highly simplified explanation of a device called a bomb calorimeter, but I think it'll do for our purposes.
Using a bomb calorimeter to measure the heat of combustion of various proteins, carbs, and fats, they determined the energy density of dietary protein = 4.1 calories / gram, carbs = 4.1 calories / gram, and fat = 9.3 calories.
The Calories - In - Calories - Out (CICO) theory of fat mass regulation relies on the first law of thermodynamics and treats the body as a bomb calorimeter.
Furthermore the human body is in complete polarity from a bomb calorimeter as it readily recognizes where calories come from.
This means that although you aren't closed system lab experiment like a bomb calorimeter, calories are still the most reliable predictor of weight and fat levels.
A long time ago, various researchers tested different food groups and found out that when they were burned in a machine called a bomb calorimeter, different foods raised the temperature of water to different levels.
Ideally, we should observe Cm, e. However, gasses diffuse and mass or energy is also lost or exchanged from the original sample (heck, when you use a «bomb calorimeter» the energy used to raise the fuel and oxygen to a combustion level and the energy introduced by the ignition «spark» are accounted for, but there are still «other» losses).
