Question
Chapter 3, Problem 11Q
Interpretation Introduction
Interpretation:
The importance of the tightly packed sample in the melting point capillary should be determined.
Concept introduction:
Temperature at which an element changes from the solid state to the liquid state is known as melting point or sometimes liquefaction point. At the melting point, both solid and liquid phase coexist in equilibrium. It depends on the pressure and is normally defined at the standard pressure
