In this lab, students will use a stainless steel temperature sensor to determine the effects of molecular size and shape on the strength of intermolecular forces for different alcohols within the same homologous series and between isomeric pairs. Heating liquid water at 67.0 C to steam at 100.0 C requires two steps: (1) heating the liquid water to its boiling point (100.0 C), and (2) converting the liquid into steam. The Clausius-Clapeyron equation cannot be used to determine.
