Chemistry Enthalpy of Paraffin Wax lab
Aim: Calculate an experimental value for the enthalpy of Combustion of paraffin wax
Variables
Independent variable: Amount of heat released by the combustion of paraffin wax
Dependant variable: Enthalpy of combustion of paraffin wax
Controls:
The candle used to release energy must be the same throughout the experiment, to ensure that the wax is the same. This will be done by only using one wax candle
The aluminium can used to heat up the water must remain the same so that it’s mass does not change due to the carbon molecules on the bottom from the heat and so that no water escapes the system. This will be done by using only one wax candle.
