What effect does antifreeze have on the melting point of ice?
Antifreeze decreases the freezing point of ice so that it melts at lower temperatures also.
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
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.
What is the changes in kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.
What effect would too rapid heating have upon apparent melting point of a compound?
The melting point of the compound would be lower than it actually is.
What is the effect of heat energy on alkali metals?
The melting point of alkali metals is low.
What Would be the effect poorly packed in melting point?
The effect of poorly packed will decrease the melting point.
Is melting point a periodic property?
A melting point is a periodic property. Melting point is basically the amount of energy required to break chemical bonds. The more energy required, the stronger the bonds and the higher the melting point. For example, Since Ionic bonds have a transfer of electrons, it requires a lot of energy to break the bonds and has a higher melting point.
Is energy required for melting?
yes. It takes energy to raise the temperature of the solid to the melting point.

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.
How does melting point of bromine change with external pressure?
Bromine, as many other materials gets a higher melting point when pressure is low [less energy is needed to set molecules free] and lower melting point when pressure is high [more energy needed].
What is the changes in kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.
