Think about intermolecular forces and the stronger the intermolecular force the more energy needed to separate the molecules. Just thinking about this, put the properties below in the correct category. Hints: Vapor pressure is high if it is easy for molecules to escape from a liquid into the gas phase. High surface tension means the liquid molecules do not separate easily Viscosity is the "thickness" of a liquid substance Strong intermolecular forces Weak intermolecular forces Answer Bank high boiling point...
