A.   fluid, because the molecules retain some mobility

B.   viscous, because the molecules can become entangled as they move past each other

C.   capillary action, because the molecules are less attracted to each other than to the walls of the container

D.   incompressible, because the molecules are relatively far apart

A.   the attractive forces between the water molecules and the walls of the container are greater than the attractive forces between the water molecules

B.   surface tension of the water causes it to "bead up" inside the container.

C.   the molecules are forced closer together because of London forces.

D.   the viscosity of the water is greater than the viscosity of the glass.

A.   the viscosity of the water is greater than the viscosity of the plastic.

B.   the hydrogen bonds between water molecules are greater than the attractions between the water molecules and the walls of the container.

C.   the molecules of water are forced closer together because of London forces.

D.   the attractive forces between the water molecules and the walls of the container are greater than the attractive forces between the water molecules.

A.   is an equilibrium partial pressure due to gas molecules.

B.   increases when the evaporation rate of a liquid increases.

C.   decreases when liquid molecules have weaker intermolecular forces.

D.   increases when liquid molecules have more kinetic energy to escape the liquid phase.

A.   predicts a linear relationship between lnP and 1/T

B.   graphing the equation produces a slope equal to −ΔHvap/R

C.   can help determine the vapor pressure of a substance at different temperatures.

D.   used only for calculating the enthalpy of vaporization of a substance

A.   melting, evaporation, sublimation

B.   freezing, vaporization, deposition

C.   melting, condensation, deposition

D.   freezing, condensation, deposition

A.   The vaporization enthalpy is always less than the condensation enthalpy.

B.   The vaporization enthalpy represents the heat released when a gas becomes a liquid, and the condensation enthalpy represents the heat required for a liquid to become a gas.

C.   There is no general relationship between these two quantities and the values depend on the substance involved.

D.   The condensation enthalpy is equal in magnitude but opposite in sign when compared to the vaporization enthalpy.
