To lament his exile, he wrote the Tristia, poems that detail his physical and emotional discomforts. Our modern day temperature scales can be traced back to no earlier than the 17th century, therefore no temperature records from Ovid's time exist. However, chemists will immediately recognize that the phenomenon of freezing-point depression can be applied to estimate the temperature of Constanta, Romania, in the year 8 A.D., provided that the composition of the wine can be accurately estimated. Throughout the Roman Empire there were many kinds of wine consumed, some of which were diluted with water. These words were used to describe undiluted wine.
Procedure Do some research on the composition of the undiluted wines made and consumed today.
Determine the actual freezing point of each of these wines. Questions Report the information obtained on the wines you researched. Include in your report the alcohol content of the wines, the type of wine, and its sugar content, if available. Calculate the expected freezing point of each of the wines provided by your instructor for the laboratory investigation. From the difference in the calculated freezing point and the measured freezing point, determine the concentration of sugar in both molal units and percent composition by weight.
