An experiment for comparing the enthalpy change of combustion of different alcohols Aim To find out the enthalpy change of combustion for a number of alcohols. Apparatus Thermometer Measuring cylinder Electrical balance Stand Burners of different alcohols (methanol ethanol propan-1-ol butan-1-ol) Water Copper can Clamp Boss Heatproof mal Matches Method 1.Measure 200cm of water (at room temperature) into the measuring cylinder; record the temperature of the water. 2.Set up the apparatus as shown below in fig 1: Thermometer Stand Copper can Thermometer Boss & clamp Copper Can Stand Alcohol burner Heatproof Fig 1. The apparatus to measure enthalpy change 3.Pour the water from the measuring cylinder into the copper can, which is on the stand and clamped in position, and put a thermometer into the water to measure the temperature change. 4.Weigh the alcohols that are to be investigated, and record the weight. 5.Place the alcohol burner under the copper can, which is on the stand. 6.Ignite the burner with a match to...
