The formula is Ek= CΔt
C is the heat capacity of the bomb calrimitor (sometimes given in question so don't worry, or you may be given the other variables and be expected to find C)
T is the temperature (initial and final)
1. Find the E absorbed (released) by the container. Ek= CΔt
2. Use the Principal of heat transfer.
Ep reaction = -Ek calorimeter
3. Find E released (absorbed) by the reaction.
(Ep = nΔΗ)
To calculate enthalpy change by bomb calorimeter, you measure the initial and final temperature of the system when a reaction occurs in the bomb calorimeter. Then, using the heat capacity of the calorimeter, mass of the reactants, and the temperature change, you can calculate the heat released or absorbed during the reaction. This heat value can be converted into enthalpy change using the equation q = mcΔT, where q is the heat released or absorbed, m is the mass of the reactants, c is the heat capacity of the calorimeter, and ΔT is the change in temperature.

What is oxygen bomb calorimeter?
An oxygen bomb calorimeter is a device used to measure the energy content of a sample by combusting it in a controlled environment and measuring the temperature change. The sample is sealed in a high-pressure vessel (the bomb) with oxygen, ignited, and the heat released is used to calculate the calorific value of the sample. This method is commonly used to determine the energy content of fuels and food.
Who invented bomb calorimeter?
Louise Therman was the scientist credited with inventing the bomb calorimeter in the late 1800s. The bomb calorimeter is a device used to measure the heat of combustion in a sample of material.
What is principle of working of bomb calorimeter?
A bomb calorimeter measures the heat of combustion of a substance by burning it inside a high-pressure vessel (bomb) filled with oxygen. The heat released during combustion is absorbed by water surrounding the bomb, which increases the temperature of the water. By measuring the temperature change and knowing the heat capacity of the calorimeter, the energy content of the substance can be calculated using the principle of conservation of energy.
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.
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 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 oxygen bomb calorimeter?
An oxygen bomb calorimeter is a device used to measure the energy content of a sample by combusting it in a controlled environment and measuring the temperature change. The sample is sealed in a high-pressure vessel (the bomb) with oxygen, ignited, and the heat released is used to calculate the calorific value of the sample.

Why 1000c thermometer is used in bomb calorimeter why not 100c?
bcoz of space in the calorimeter....

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
Why bomb calorimeter is called by that name?
The bomb calorimeter gets its name from the sealed vessel (or "bomb") used to hold the sample during combustion. This vessel is designed to withstand high pressure and allow for accurate measurement of the heat released during the reaction.
What is principle of working of bomb calorimeter?
A bomb calorimeter measures the heat of combustion of a substance by burning it inside a high-pressure vessel (bomb) filled with oxygen. The heat released during combustion is absorbed by water surrounding the bomb, which increases the temperature of the water.

A device used to calculate the amount of heat energy stored in foods?
A bomb calorimeter is a device used to measure the amount of heat energy stored in foods. It works by burning a sample of the food in an oxygen-rich environment and measuring the temperature change in the surrounding water bath to calculate the energy content of the food.
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 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 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.
