Calorimeters measure the quantity of heat energy involved in processes such as heating, chemical reactions, changes of state, and mixing of substances. The unit of energy in the International System of Units is the joule. Another unit still being used is the http://www.answers.com/topic/calorie, defined as 4.184 http://www.answers.com/topic/joule. One type of calorimeter contains a combustion chamber surrounded by water. When matter is placed in the chamber and physically or chemically changed (usually by burning), the temperature change of the surrounding water is measured and used to determine the energy (calorie) content of the sample.

∙ 9y agoCalorimetry is the science of measuring the amount of heat of reactions. The heat reactions are measured with a Calorimeter. There are two basic types of calorimetry: measurements based on constant pressure and measurement based on constant volume.

∙ 15y agoThis depends entirely on what type of calorimeter you are using. If you are using a bomb calorimeter it works by ignition a spark that burns a sample that you want to know the amount of calories in. This "bomb" causes the water in a tank to heat up and you measure the temperature change in that water for about 45 minutes. Then you use equations to figure out how many calories were burnt based on the temperature change. Temperature change is also the source for many other colorimeters.

What method is used to measure the amount of heat given off by the body?
Direct calorimetry
What is the principle behind microbial calorimetry?
Basically all the reacitons in living systems are thermodynamic. Some of thems are exergonic which liberate heat energy and some are endergonic which utilize heat energy. Same type of reactions utilize or liberate same amount of heat energy. This energy will be constant for a particular reaction. The amount of heat liberated by same type of reactions in any microbial culture will be directly proportional to the number of microbes. So by finding the amount of heat energy produced or utilized by any microbial culture one can estimate the number of microbes present in that culture. This is the principle behind microbial calorimetry. S.Manu. Lecturer, MVJ College of Engineering, Bangalore. The number of microbes may not be accurate but it will be in the range. It depends on different aciviteis of the microbes and the growth phase of the microbes. They liberate different amonut of heat in different phases. So many correction factors are needed to make out correct number of microbes in a culture.
What is cascading principle?
If you mean the cascade principle; that is a principle connected to evolution in Cellbiology.
What rule or principle states that no two electrons in the same orbital can have the same spin?
This is the Pauli exclusion principle. Wolfgang Pauli was a Jewish physicist, Nobel prize laureate.
On what principle does calorimetry depends?
law of conservation of energy.
What are the principles of calorimetry?
Isothermal Principle: total heat elimination = heat loss by radiation + convection + conduction + evaporation
Does calorimetry measure alcohol intake?
calorimetry=amount of calories you intake, not alcohol
What is a calorimetry?
A calorimetry is a wide headband which covers the ears, suitable for wearing on cold days.
What is the relationship between heat and calorimetry?
heat is a form of energy. where as "calorimetry" is the study of energy or study of heat. calorimetry not only deals with heat but also with other forms of energy.
