Determination of the enthalpy of vaporisation of liquids with CobraSMARTsense

The vaporisation of a liquid occurs with heat absorption. To determine the enthalpy of vaporisation, a known mass of the liquid which is to be investigated is vaporised in a special vaporisation vessel in a current of air. The quantity of heat absorbed, which corresponds to the enthalpy of vaporisation, can be calorimetrically determined. Simplified implementation: all pre-settings already prepared Part of a system solution - Easily expandable for further experiments Calorimeters with particularly high capacitance Determine the molar enthalpy of vaporisation of diethyl ether and methanol. Calculate the molar entropies of vaporisation and discuss the results under consideration of Trouton's rule.
