Show in each case the effect of pressure on the melting point. If not, state why not. Partial credit will be awarded for the correct approach even if your answer is wrong. Use the back of these sheets if necessary. Partial pressure data as a function of composition for a solution of acetone and chloroform are given in the table below and also plotted at right.
Some liquid crystals exhibit what are known as re-entrant phases , as shown on the diagram below.
At certain temperatures as the pressure increases, one observes a transition from phase b to phase a followed by a transition back to the b phase, as shown by the dashed line.
