1) Reduce the partial derivative (πΞΌππ)π. The answer must be in terms of the thermodynamic properties πΌ,πππππππ.
2) A particular system, containing 1 mol, is taken from state A to state B through a process that obeys ππ£1/2=ππππ π‘.Knowing that during this process πΌ=ππβ1, ππ=πand ππ=ππ£2are known and π,π,πare positive constants, determine the temperature variation of this system during this process in terms of the known values of states A and B.
3) In the neighborhood of the triple point the vapor pressure of a liquid is given bylnπ=π΄βπ΅πWhere π΄and π΅are positive constants. This is the equation of the liquid-vapor transition curve in the T-P plane. Similarly, the vapor pressure of the solid of the same substance is given bylnπ=πΆβπ·πwhere C and D are also positive constants. Determine the temperature and the pressure at the triple point.Calculate the latent heat of sublimation and vaporization for this substance. Finally, determine, in the triple point, the corresponding latent heat of fusion.
