A calorie (in this context) is the amount of heat energy required to heat 1 gram of water one degree, typically measured in joules (units of energy). A calorie is equal to approximately 4.184 joules.

∙ 11y agoWe know that a gram of water heats up 4.18 degrees celcius when 1 joule of energy gets transterred to it. We keep that water in a container where nothing on the outside can transfer much heat to the water. Only the heat coming off of a
chemical reaction
will heat that water.
If we measure the temperature of the water when the chemical reaction is over, we can calculate how much energy that chemical reaction put out.
Think of the water as a heat sink from which no heat can escape. That is the essence of a calorimeter.

What are the use of a calorimeter?
A calorimeter is a device used for calorimetry, the science of measuring the heat of chemical reactions or physical changes as well as heat capacity. The word calorimeter is derived from the Latin word calore, meaning heat. Differential scanning calorimeters, isothermal microcalorimeters, titration calorimeters and accelerated rate calorimeters are among the most common types. A simple calorimeter just consists of a thermometer attached to a metal container full of water suspended above a combustion chamber.
Is work done a scalar or a vector quantity?
Work done is the amount of energy transferred by a force acting through a distance. It is a scalar quantity.
Is power is a vector quantity?
No, power is not a vector quantity. It is a scalar quantity because it only has magnitude, not direction. Power is defined as the rate at which work is done or energy is transferred.
How does the chemical formula of a compound relate to the relative number of atoms in the compound?
Chemical formulas consist of chemical symbols and numbers. The symbols represent the elements in the compound. The numbers indicate the quantity of atoms of each element in the compound.
What is the principle of calorimetry?
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.
What measures the heat of the chemical reactions?
A calorimeter is a device used to measure the quantity of heat flow in a chemical reaction. Two of the most common types of calorimeters are the coffee cup calorimeter and the bomb calorimeter..........For more info., referSpecial:UnAnsweredQ
