Is the melting point of impure water lower or higher than freezing point?
The boiling Point of impure water is 100 degrees celsius
What is the melting and boiling points of magnesium and chloride?
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.
Effect of impurities on melting point and melting point?
According to RAOULT, when two different metals of different melting points are melted or alloyed there melting points considerably change. So,according to the percentage of impurities, the melting points either increase or decrease.
What temperature will a substance melt if the atmospheric pressure is 1.2?
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).
What effect would increasing the quantity of paradichlorobenzene have on the melting point temperature?
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.
Will there be effect on melting or boiling point of a substance if another substance is added to it?
Yes, impurities have important effects on the melting and boiling point of materials.
Does soluble impurities effect boiling?
yes
Is the melting point of impure water lower or higher than freezing point?
The boiling Point of impure water is 100 degrees celsius
How does impurities in water effect its boiling point?
Depending on what is in it, the boiling point will either rise or fall.
What effect would contaminating the sample with an insoluble impurity have on the melting point?
Soluble impurities (that is, impurities that are included within the crystal matrix) tend to lower the observed melting point and broaden the melting point range. Insoluble impurities have no effect on the melting point. Found from website: http://swc2.hccs.edu/pahlavan/2423L1.pdf
What is the effect of impurities on the melting point of ice and the boiling point of water?
The freezing point of water decreases when the number of dissolved molecules (or better particles) in the solvent increases. This is called freezing point depression and you can easily find the relation between the quantity of particles dissolved and the freezing point on Wikipedia.
What is the effect of impurities on boiling point of different chemicals?
It varies. A saturated solution of NaCl in water increases the boiling point, higher than 100oC. I suppose most impurities increase the boiling point.
What is the melting and boiling points of magnesium and chloride?
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.

Properties that affects the melting and boiling points of a molecule?
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.
What temperature will a substance melt if the atmospheric pressure is 1.2?
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).
How does pressure and impurities affects boiling point?
Boiling is used to describe a change of state of a pure liquid to vapour phase. The particular temperature at which this change of state occurs is defined as the boiling point of that specific liquid. Now the question is will addition of impurities have any effect on the boiling point of water. The addition of impurities such as salt or sugar to pure water raises its boiling point.
