kaffekoppkalorimeter
The kaffekoppkalorimeter, or coffee cup calorimeter, is a simple constant-pressure calorimeter used to measure the heat change of reactions conducted in aqueous solution. It typically consists of two nested Styrofoam cups, a lid with a hole for a thermometer, and minimal heat exchange with the surroundings. The inner cup holds the reacting solution, while the insulating setup reduces heat loss to the environment, making it suitable for teaching and small-scale experiments.
Principle and calculation: When a reaction occurs in the solution, heat is absorbed by the solution and
Procedure and calibration: A known amount of solute is dissolved or reacted, the temperature change is recorded,
Applications and limitations: The coffee cup calorimeter is widely used in introductory chemistry labs to estimate
