Is a bomb calorimeter accurate?
Yes, a bomb calorimeter is known for its high accuracy in measuring heat of combustion for various substances. It can provide precise measurements by keeping the system isolated and accounting for all heat transfer mechanisms.
What are the differences between simple calorimeter and bomb calorimeter?
A simple calorimeter measures heat changes in a substance through temperature changes in water surrounding it, while a bomb calorimeter measures the heat of combustion of a substance by igniting it in a sealed chamber under high pressure. Bomb calorimeters are more precise and accurate than simple calorimeters, but they are also more complex and expensive to operate.
What are the advantages and disadvantages of bomb calorimeter?
Advantages of bomb calorimeter: provides highly accurate measurements of the energy content of a sample, can be used to analyze a wide range of sample types, and allows for precise control of experimental conditions. Disadvantages of bomb calorimeter: expensive to purchase and maintain, time-consuming to set up and conduct experiments, and requires specialized training to operate correctly.
Who invented bomb calorimeter?
French scientist and statesman, Berthelot (1827-1907) in 1881
How do you calculate the heat capacity of a bomb calorimeter?
To calculate the heat capacity of a bomb calorimeter, you can use the formula Q C x T, where Q is the heat absorbed or released, C is the heat capacity of the calorimeter, and T is the change in temperature. By measuring the heat absorbed or released and the change in temperature, you can determine the heat capacity of the bomb calorimeter.
Why bomb calorimeter is called by that name?
In conducting a calorimetric test using a bomb calorimeter, the substance or object to be studied is placed inside the combustion crucible and ignited. The resulting reaction usually occurs so quickly that it resembles the explosion of a bomb-hence, the name "bomb calorimeter."

What does a bomb calorimeter identify and measure in a scientific experiment?
A bomb calorimeter identifies and measures the amount of energy released when a substance is burned in a controlled environment, providing information about the substance's energy content.
What apparatus is used in determining quantities of heat in substances or chemical processes such as combustion?
A bomb calorimeter or Differential Scanning Calorimeter (DSC)
What is the difference between a bomb calorimeter and a coffee cup calorimeter?
A bomb calorimeter is a sealed device used to measure the heat of combustion of a substance under constant volume, typically in a controlled environment, allowing for high-pressure reactions. In contrast, a coffee cup calorimeter is an open system that measures heat changes in reactions occurring at constant pressure, making it suitable for simpler experiments like neutralization or dissolution in aqueous solutions. The bomb calorimeter is designed for high-energy reactions, while the coffee cup calorimeter is more suited for less intense reactions.
Is volume constant in bomb calorimeter?
In a bomb calorimeter, the volume is not constant; it is typically operated under constant volume conditions. This means that the reaction occurs in a rigid, sealed container where the volume does not change during the combustion process. The constant volume allows for accurate measurement of the heat released during the reaction, which is essential for calculating the calorific value of the substance being tested.
