Calorimeter Process

Postby PwintN 2H » Sun Jan 10, 2016 8:11 pm

How does a calorimeter work to measure specific heat? Not in terms of calculations, but in terms of process and in practice.

A calorimeter measures the heat created by a sample that is burned (combusted) in a closed vessel. The sample is burned in an oxygen atmosphere, surrounded by water, and under constant conditions. The heat created by the combustion is transferred to the surrounding water, and that is how the heat is measured (presumably by the difference in the water's temperature). One can find the specific heat by burning exactly 1 gram of the substance.
