Intermolecular Forces

Evaporation and Inter molecular Attractions In this experiment, Temperature Probes are placed in various liquids. Evaporation occurs when the probe is removed from the liquids container. This evaporation is an endothermic process that results in a temperature decrease. The hunting lodge of a temperature decrease is, like viscosity and boiling temperature, think to the strength of intermolecular forces of attraction. In this experiment, you volition study temperature changes ca delectationd by the evaporation of some(prenominal) liquids and relate the temperature changes to the strength of intermolecular forces of attraction. You entrust up stakes use the results to predict, and then measure, the temperature change for several(prenominal)(prenominal) other liquids. You will encounter 2 types of organic compounds in this experimentalkanes and alcohols. The cardinal alkanes are pentane, C5H12, and hexane, C6H14. In addition to carbon copy and hydrogen atoms, alcohols ex cessively contain the -OH functional group. Methanol, CH3OH, and ethanol, C2H5OH, are two of the alcohols that we will use in this experiment. You will examine the molecular structure of alkanes and alcohols for the front line and relative strength of two intermolecular forceshydrogen stick and dispersion forces. OBJECTIVES IN THIS EXPERIMENT, YOU pluck up stakes * Study temperature changes caused by the evaporation of several liquids. * Relate the temperature changes to the strength of intermolecular forces of attraction.
