  • 1

    is a phenomenon between liquids and gases. It causes objects that usually sink due to their higher density to swim.

    Surface tension

  • 2

    the resistance of a liquid to flow. The greater the viscosity, the slower the liquid flows.

    Viscosity

  • 3

    a pressure exerted by molecules that have enough energy to escape the surface, as Temperature ↑, Vapor Pressure ↑, Evaporation ↑

    Vapor pressure

  • 4

    The _________is the temperature at which the vapor pressure of a liquid is equal to the external pressure. The boiling point of a liquid is the temperature at which the liquid converts into a gas. The normal boiling point is the temperature at which the liquid converts to a gas when the external pressure is 1 atm. The normal boiling point of water is 100oC

    Boiling point

  • 5

    the _____________ is the energy required to vaporize 1 mole of a liquid at a given temperature. H is the symbol for enthalpy, which means heat content at a given standard condition.

    Molar heat of vaporization (ΔHvap)
