In a bomb calorimeter, the primary focus is on measuring the heat released during a chemical reaction at constant volume. The condensation of water is not included because it occurs at a constant temperature and pressure, which can introduce additional heat exchanges and complicate the measurements. Including condensation would also affect the accuracy of the specific heat calculations, as it involves phase changes that do not directly relate to the reaction's heat release. Therefore, the system is designed to minimize such factors for precise calorimetric measurements.

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.
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."
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]
A 0.48g sample of graphite is placed in a bomb calorimeter with an excess of oxygen The water and calorimeter are at 25 c The graphite is ignited and burned and the water temperature rises to 28.05c?
The heat released by burning the graphite can be calculated using the temperature rise of the water and the heat capacity of the calorimeter. Firstly, calculate the heat absorbed by the water: Q = m * c * ΔT, where m is the mass of water and c is its specific heat capacity. Then, subtract the heat absorbed by the water from the total heat released by the graphite to find the heat produced by the combustion of the graphite.
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.

Why 1000c thermometer is used in bomb calorimeter why not 100c?
bcoz of space in the calorimeter....
What is thre function of a bomb calorimeter?
it burns food and that heats water to give a reading in calories
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 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.
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 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 is bomb caloriemeter?
A bomb calorimeter is a device used to measure the heat of combustion of a substance. It consists of a sealed container (the bomb) where the substance is burned, surrounded by a known amount of water. The heat released during combustion raises the temperature of the water, allowing the calculation of the heat of combustion of the substance.

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)
