High School Chemistry
A simple calorimetry experiment using a spirit burner and a copper calorimeter.
Ethanol was used to heat 120ml water in a copper calorimeter.
The spirit burner containing the ethanol was weighed on an electronic balance before and after heating.
The water was stirred continuously and an 8 C rise in temperature was recorded for the water.
Some of the major errors were discussed
For example, heat loss to the equipment and surroundings, impure ethanol, incomplete combustion and inaccurate temperature measurement.
