Biphenyl freezing point
WebThe experimental freezing point is the temperature at which these two lines intersect. This is shown in Figure 2. The freezing point of a liquid and the melting point of a solid occur at the same temperature. This temperature is defined as the point at which the solid and liquid phases coexist in equilibrium with each other under a given pressure. http://docott.com/files.142/labs.exams/Steric.acid.FP.depression.htm
