| Abstract: | For "determination of naphthalene molecular weight with freezing point depression" in physics chemistry experiment,the semi-conductor system cold freezing point measurement instrument was researched and manufactured.Automatic calculation and determination of molecular weight were carried out,and the existent problem in old style experiment equipment was overcame.By determining the freezing point of hexahydrobenzene and molecular weight of naphthalene,the instrument was validated to be dependable.The influence factors of freezing point with the speed of beater and refrigeration temperature were also discussed. |
