The frame of a "Vinyl" window is made out of PVC (Polyvinylchloride). The properties of PVC will depend on the additives and other components added during the compounding step. Straight PVC has a melting point around 85 oC. Higher heat resistant PVC has a melting point around 180 oC.
diamond has a 3 dimensional frame work of carbon and hence has high melting point
For example the melting point of acetylene -80,8 oC.
The melting point of the candle is 47 Celsius.
Example: compounds that are thermally decomposed before a supposed melting or boiling point.
It is the opposite. The boiling point is greater than the melting point. for example for fresh water, the boiling point is 100 centigrade while the melting point (for ice) is zero.
I use Petroleum Jelly, (Vaseline) in my wax and it lowers the melting point a bit.
when we lower the melting point of of ice for example from 00C TO -20C, as the temperature is 00C that is above the new melting point of ice so ice get melt
Molecular Solids have a lower melting point
This is the melting point.
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.
Ionic compound with high melting and boiling point. This is good example of a salt.
