Document Summary

The course will use the celsius scale denoted by c. This scale is based on the freezing of pure water at 0 c and the boiling of pure water at 100 c. C base line ice water bath intermediary boiling water temperature water bath bath. The course will also use the kelvin scale denoted by k. there is no degree sign in this symbol. This scale is based on a conversion from the celsius scale which is. The temperature at which all molecular motion stops is. Properties of a pure substance that undergoes a change of phase. *some figures of this lecture are taken from http://engr. bd. psu. edu/davej/classes/thermo/chapter2. html. Compressed liquid: not about to vaporize (sub-cooed liquid) e. g. , water at 20oc and 1 atmosphere. Saturated liquid: about to vaporize e. g. , water at 100oc and 1 atmosphere. Saturated vapor: about to condense e. g. , water vapor (steam) at 100oc and 1 atm.
