Problem: If the thermal expansion coefficient of a material is positive, does the entropy of the material (i) increase or (ii) decrease as the pressure increases while keeping temperature constant?

The activity of O2 at 1 atm is higher than activity of O2 at 10-2atm), true or false?

If the thermodynamic driving force for solidification of a liquid (the Gibbs free energy difference between solid and liquid) varies with temperature linearly, determine whether the heat capacity difference between the solid and liquid is (i) 0, (ii) constant, or (iii) linear as a function of temperature.

The higher the heat of vaporization of a liquid, the higher the equilibrium vapor pressure above the liquid at a given temperature and under 1atm total pressure: true or false?

For an engine to reach the ideal, maximum thermodynamic efficiency, all the processes involved in the engine cycle have to be reversible, true or false?

For an engine operating between a high temperature heat source at 1500K and a low temperature heat sink at 300K, what is the maximum possible efficiency?

The higher the temperature of the high temperature heat source, the higher the engine efficiency is, true or false?
