Enthalpy – Simple calorimetry, Combustions of alcohols

Enthalpy – Simple calorimetry, Combustions of alcohols

In this experiment, you'll be measuring the heat of combustion of a series of five primary alcohols, from methanol to pentanol. By burning a measured mass of an alcohol in a spirit lamp and transferring the heat energy released to a calorimeter containing water, you'll be able to calculate the heat of combustion. The experiment requires safety glasses, a thermometer, a calorimeter, and the primary alcohols, which are flammable and potentially poisonous. Once completed, you'll be able to plot a graph of your results and draw conclusions from the data.

Cooling Curve

Cooling Curve

A cooling curve is a graph that shows the change in temperature of a substance over time as it cools down from a melted state to a solid state. This type of experiment can be useful for studying the cooling behaviour of substances and can also provide information about the purity and crystalline structure of the substance.
