- The viscosity of a multigrade motor oil (such as one rated10W-40) is less temperature dependent than the viscosities ofmost substances. These oils contain polymers (long moleculescomposed of repeating units) that coil up at low temperatures butunwind at higher temperatures. Explain how the addition ofthese polymers to the motor oil might make the viscosity lesstemperature dependent than a normal liquid.The viscosities of five liquids at 25°C are given in the following table. Explain the observed trends in viscosity.Equation 22.6 defines surface tension in terms of Gibbs energy. Borrowing an analogy from chemical potential, we submit that surface tension can also be defined in terms of enthalpy, internal energy, or Helmholtz energy. Write partial derivatives for those definitions.
