Energy affects melting point by influencing the kinetic energy of the particles within a solid. As energy is added, typically in the form of heat, the particles vibrate more vigorously, eventually overcoming the intermolecular forces holding them in a fixed position. This results in a phase transition from solid to liquid at the melting point. Conversely, a decrease in energy can lower the temperature, potentially raising the melting point by stabilizing the solid phase.
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
Yes, impurities have important effects on the melting and boiling point of materials.
The kinetic energy increase.
Salt water has a lower freezing point and a higher boiling point.
The melting point of borax is 743 oC.
The melting point of alkali metals is low.
The effect of poorly packed will decrease the melting point.

As a substance is heated to its melting point, the kinetic energy of its particles increases, causing them to move more rapidly. This increase in kinetic energy leads to a rise in temperature until the substance reaches its melting point. At the melting point, the kinetic energy is used to overcome the forces holding the particles together, leading to the substance changing from a solid to a liquid state.

The energy associated with melting is called heat of fusion. It is the amount of energy required to change a substance from a solid to a liquid state at its melting point.
yes absolutely.......
The kinetic energy increase.
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.
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.
solidifying or freezing, releasing energy to the environment.
Rock salt lowers the freezing point of water, causing the ice to melt. This melting process requires energy, which is absorbed from the surroundings, resulting in a cooling effect.
