Which pair of liquids listed below is miscible?

• Benzene and water

• Water and olive oil

• Castor oil and glycerol

• Benzene and glycerol

• Water and glycerol

Viscosity and surface tension decrease with increasing temperature. This is

most accurately explained by the fact that

• liquids expand when heated,

  increasing the distance between the molecules.

• both viscosity and surface tension are primarily determined by the

  intermolecular forces of attraction between the molecules in the liquid.

• density decreases with increasing temperature, allowing the molecules

  to flow more freely past each other.

• increasing temperature increases reaction rates.

• increasing temperature increases the Keq of the equilibrium state of

  both the viscosity and surface tension.
