ЧТО ОЗНАЧАЕТ СЛОВО BOMB CALORIMETER
калориметр
Калориметр - это объект, используемый для калориметрии, или процесс измерения тепла химических реакций или физических изменений, а также теплоемкости. Среди наиболее распространенных типов - дифференциальные сканирующие калориметры, изотермические микрокалориметры, калориметры титрования и ускоренные калориметры скорости. Простой калориметр состоит только из термометра, прикрепленного к металлическому контейнеру, наполненному водой, подвешенной над камерой сгорания. Чтобы найти изменение энтальпии на моль вещества А в реакции между двумя веществами А и В, вещества добавляются в калориметр, и отмечаются начальная и конечная температуры. Умножение изменения температуры на массу и удельные теплоемкости веществ дает значение для энергии, выделяемой или поглощенной во время реакции. Разделение изменения энергии на сколько молей А присутствовало, дает изменение энтальпии реакции. Этот метод используется в основном в академическом обучении, поскольку он описывает теорию калориметрии. Он не учитывает потери тепла через контейнер или теплоемкость термометра и самого контейнера.

Chemistry: Principles and Reactions
A sample of fructose, C6H12O6, weighing 4.50 g is burned in a bomb calorimeter
that contains 1.00 L of water (d = 1.00 g/mL). The heat capacity of the calorimeter
is 16.97 kJ/8C. The temperature of the calorimeter and water rise from 23.498C ...

9.4 THE BOMB CALORIMETER A bomb calorimeter is an apparatus that is used
to determine the calorific value of a fuel practically. The combustion of the fuel
takes place at constant volume and at a high pressure (approximately 2.3 MPa)

bomb calorimeter during the determination of calorific value. The latent heat of
condensation of steam also gets included in the measured heat resulting in a
higher value and hence the bomb calorimeter experiment actually determines the

Chemistry: The Practical Science
We can achieve this using a technique called constant-volume calorimetry, in
which the reacting system is sealed within a steel chamber of fixed volume,
called a bomb calorimeter, shown in Figure 5.16. When a combustion reaction is

Principles of Chemistry: The Molecular Science
Often, in finding heats of combustion or the caloric value of foods, where at least
one of the reactants is a gas, the measurement is done at a constant volume in a
bomb calorimeter (Figure 6.16). The “bomb” is a cylinder about the size of a ...

It should be noted that bomb calorimeter measures the higher or gross calorific
value because the fuel sample is burnt at a constant volume in the bomb. Further
