The aim of this experiment was to determine the enthalpy of combustion of ethanol. List the five measurements that were made during the experiment
- Initial mass of burner
- Final mass of burner
- Intital temperature (water)
- Final temperature (water)
- Volume of water
What are the three formula needed to work out the enthalpy of combustion?
- E = cmΔT
- n = mass / FM
- ΔH = E / n
What kind of error in the experiment could cause the enthalpy of combustion in the experiment to differ from the real enthalpy of combustion?
- Heat loss to the surroundings
- Incomplete combustion of ethanol
