Yes, impurities have important effects on the melting and boiling point of materials.
The melting point and boiling point of a substance come under the category of phase changes. And the temperature at which these phase changes occur are related to the intermolecular forces holding the molecules of the substance together.
Each substance has a different effect on the boiling point.
Salt water has a lower freezing point and a higher boiling point.
No.It is a physical property of a substance.
returning condensate is rich in high boiling point allowing lower boiling point substance to distill over.
chloride isn't a thing on its own and the melting and boiling points of chlorine and magnesium will have no effect on the boiling and melting point og magnesium chloride.
The melting point and boiling point of a substance come under the category of phase changes. And the temperature at which these phase changes occur are related to the intermolecular forces holding the molecules of the substance together.
Leaving aside the obvious deficiencies in the question (1.2 WHAT? What substance?)... For most substances pressure has only a tiny effect on the melting point, and enormous pressures are required to change the melting point significantly (in contrast to boiling point, where pressure has a relatively much greater effect).
Pressure
The melting point of the substance should not change as all substances have specific melting, boiling, condensation, and freezing points. It would, however, require more energy (in this case, heat) to melt the increased quantity of paradichlorobenzene in the same amount of time.
The boiling point depends on altitude (pressure). The effect on the melting point is not significant.
Each substance has a different effect on the boiling point.
The boiling Point of impure water is 100 degrees celsius
The atomic structure of an atom determines what it is able to bond with. It will also effect its boiling and melting point.

A soluble volatile substance will lower the boiling point of a solution. The volatile substance will boil at a lower temperature than the water component, thus causing the solution to boil at a lower temperature.
