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 is the principle of Bunsen calorimeter?
The Bunsen calorimeter principle is based on the law of conservation of energy, where the heat released or absorbed in a chemical reaction is equal to the heat gained or lost by the surrounding water in the calorimeter. By measuring the temperature change of the water, one can calculate the heat exchanged in the reaction.
What is the name for a device that provides a thermally isolated environment in which substances exchange heat?
The device you are referring to is called a calorimeter. It is specifically designed to measure the heat exchange between substances in a thermally isolated environment.
Function of calorimeter?
A bomb calorimeter is a type of constant-volume calorimeter used in measuring the heat of combustion of a particular reaction. Bomb calorimeters have to withstand the large pressure within the calorimeter as the reaction is being measured. Electrical energy is used to ignite the fuel; as the fuel is burning, it will heat up the surrounding air, which expands and escapes through a tube that leads the air out of the calorimeter. When the air is escaping through the copper tube it will also heat up the water outside the tube. The temperature of the water allows for calculating the calorie content of the fuel.[ or kilojoules if using those units]
What can be used as a calorimeter?
Common materials that can be used as a calorimeter include a styrofoam cup, a metal canister, or a bomb calorimeter. These materials are used to measure heat exchanges during chemical reactions or physical processes.
How do you use a calorimeter?
A calorimeter is used to keep heat contained in a single place as the calorimeter absorbs very little heat and the amount it absorbs can easily be calculated. To use the calorimeter heat the liquid you want (or cool) and place it in the calorimeter cup and put that in the calorimeter and place the lid on top and the thermometer in the thermometer's hole. There you go. Simple as that. A calorimeter is used to keep heat contained in a single place as the calorimeter absorbs very little heat and the amount it absorbs can easily be calculated.

Why 1000c thermometer is used in bomb calorimeter why not 100c?
bcoz of space in the calorimeter....
Who invented bomb calorimeter?
French scientist and statesman, Berthelot (1827-1907) in 1881
What is the conclusion of the bomb calorimeter experiment to determine the calorific values of fuel by means of a bomb calorimeter?
it is for determining gross calorific value of any coal
How do you test how much energy is in a fuel?
One way would be to use a device called a bomb calorimeter. (Despite the name, it doesn't actually explode. Or at least it's not supposed to.)
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.
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.
How to perform bomb calorimetry for measuring energy content in a sample?
To perform bomb calorimetry for measuring energy content in a sample, first place the sample in a sealed container called a bomb calorimeter. Ignite the sample to burn it completely, releasing heat. Measure the temperature change in the calorimeter to calculate the energy content of the sample.
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)

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 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.
