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?
bomb calorimeter is heat combustion
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?
-392.5 kJ/mol
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]
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.

What is the name for a device that provides a thermally isolated environment in which substances exchange heat?
calorimeter
What is the principle of Bunsen calorimeter?
bomb calorimeter is heat combustion
What are the different types of calorimeters?
Bomb calorimeter and coffee-cup calorimeter. Both useful, however, the bomb calorimeter is better to use if you're measuring deltaH of a gas
Why 1000c thermometer is used in bomb calorimeter why not 100c?
bcoz of space in the calorimeter....
What are the differences between simple calorimeter and bomb calorimeter?
bomb calorimeter measures heat transfer at constant while the cup measures at constant pressure.
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.)
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)

How does a scientist find out how much energy is in food?
By burning a dried sample of it in a device called a "bomb calorimeter" with pure oxygen and measuring how much heat is released by the temperature rise in a water jacket around the "bomb".
Who invented bomb calorimeter?
French scientist and statesman, Berthelot (1827-1907) in 1881
What is bomb caloriemeter?
Bomb calorimeter is the apparatus used to find the change in internal energy with respect to heat capacity at constant pressure.
What is a bomb calorimeter used for?
A calorimeter is a device used to measure the heat levels produced by chemical reactions. Bomb calorimeters are heavy-duty devices to withstand greater levels of heat combustion and pressure. Bomb calorimeters are used in many industries such as the oil and gas industry or food industry.
