no, not at all
I use Petroleum Jelly, (Vaseline) in my wax and it lowers the melting point a bit.
At thirty-three degrees Fahrenheit ice cubes will melt in diet coke.
Neither since the melting point of sugar is 365 F and the melting point of salt is 1474 F
Sugar has very little effect on melting point - it is too high molecular weight. That might answer your question, which does not make sense as written. Thus, it melts faster with sugar, because other ice cubes slow melting.
There are hundreds of different glues, with different melting points, setting times and means of adhesion.

No. The phase change requires adding heat, so melting ice cubes is an endothermic reaction.
This is the melting point.
melting point
Almost all solids will turn into liquid at some temperature.This process is called melting and the temperature at which the solid melts is its melting point.
