Role of stirbar that is normally added to liquid to be boiled should be determined. Concept introduction: Conversion of substance from its liquid to vapor state is called boiling. Boiling point is defined as temperature that has vapor pressure of liquid equal to pressure that is present around liquid. At this temperature, substance gets converted from liquid state to vapor or gaseous phase. It depends on strength of intermolecular forces. Stronger the intermolecular forces, higher will be boiling point and vice-versa.

Briefly describe the technique for packing a capillary melting point-tube

Filter paper is usually a poor material on which to powder a solid sample before introducing it into a capillary melting-point tube because small particles of paper may end up in the tube along with the sample. Why is this undesirable? and how might the presence of paper in the sample make the melting-point determination difficult
