Explanation / Answer

1. when part of the solid start melting then temperature must record. since heating of all the part of solid is not unifrom so, some time is require to melt the full part of solid in mean time temperature of instument temperature may increase which will not be actual melting point.

2. Enerngy require to breake crystal intramolecular attraction force is called melting point. If the solid is mixture of amorphus and crystal then amorphous part will melt frist so we will get a range. Hare in the compound impurity is present but solid is mixture amorphous and different morphology.

3. i) coloration of substance

    ii) decomposition of substance

    iii) if the solid is not crystal then we will get range of melting point

    iv) if solvent traped in solid then evaporation of solvent cause difficulty

    v) if uniformity of heating is present.

4. 10 to 15 sentence for introduction is apt

5. physical proterty should noted

   i) room temperature

ii) coloure of compound

iii) solubility

iv) melting point and boling point
