For SO2 melting and boiling points are 198 K and 263 K respectively. ĈPvalues forsolid phase are 1.255 J/mol-K at 15 K and 84.185 J/mol-K for greater than 15 K.ĈPvalues for liquid phase is 24.937 J/mol-K. For gas phase ĈP = 49.769 + 4.56*10-3T J/mol-k where T is in K. Enthalpy of freezing and condensation processes are -7.402kJ/mol and -24.937 kJ/mol respectively. Determine specific entropy of SO2 at 400 K.

J 5 The Tin-Bismuth phase diagram is shown below. DSC was used to analyse three samples in the Sn-Bi system. Sample 1 has the composition 40 wt% Bi – 60 wt% Sn, Sample 2 has the composition 57 wt% Bi – 43 wt% Sn, and Sample 3 has the composition 100 wt% Sn. Using the information from the phase diagram, draw graphs of the expected DSC curves for the three samples on heating from 50°C to 300°C. Label the axes and curves

2. A liquid at 1000°C and an overall composition of 55% zinc (45% copper) is cooled to 600 C. a. What phases are present? b. What are the compositions of each phase? What are the mass fractions of each phase? с.
What is the difference between a state and a microstate of a system? Check all that apply. A thermodynamic state is a single possible arrangement of the positions and kinetic energies of the molecules. A thermodynamic state is a set of conditions, usually temperature, volume, and number of moles, that defines the properties of a bulk material. A microstate is a single possibility for all the positions and kinetic energies of all the molecules in a sample. A microstate is a snapshot of positions and speeds at a particular instant. A thermodynamic state is a set of conditions, usually temperature and pressure, that defines the properties of a bulk material.
