What is the principle of Bunsen calorimeter?
bomb calorimeter is heat combustion
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]
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."
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
Difference between isothermal and isoperibol calorimeter?
An isothermal calorimeter is a tool used to bind small molecules to larger macromolecules, and determine the thermodynamic parameters of interactions in a solution. An isoperibol calorimeter measures the heat created by a sample burned under an oxygen atmosphere in a closed vessel surrounded by water, in controlled conditions. The measurement is known as a BTU value.
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 instrument measures the heat released at constant volume?
a calorimeter
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 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 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
What is the unit for the calorimeter constant?
joul per k
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)
