Calorimetry

Determination of the heat of formation of water

Determination of the heat of formation of CO2 and CO and Hess's law

Determination of the heating values of solid and gaseous fuels in a horizontal calorimeter

Principle

In order to determine the heating capacities of commercially available solid fuels (coal, coke, lignite, peat, wood etc), pieces weighing 0.5 to 1 g are used. Wood and peat have to be air-dried, and coal and lignite have to be stored under dry conditions. In ord ...

Determination of the calorific value of food stuffs

Principle

In order to determine the heating capacities of commercially available solid fuels (coal, coke, lignite, peat, etc), pieces weighing 0.5 to 1 g are used. Wood and peat have to be air-dried, and coal and lignite have to be stored under dry conditions.

Determination of the heating values of liquids in a vertical calorimeter

Determination of enthalpies of combustion

Principle

To determine the enthalpy of combustion of high-boiling-point, low-flammability liquids such as olive oil, they are burned in a pure oxygen atmosphere. The substances to be burned are placed in a small glass container, which is placed into the vertically arrange ...
