How do intermolecular forces of attraction define the properties and uses of matter? Using the concepts of bond polarity and solubility, explain why ethanol (rubbing alcohol) and water are miscible, but oil and water are immiscible. Using the concept of intermolecular forces of attraction, explain why butter remains solid when refrigerated, but melts at room temperature or when heated.
