It's not what's in sugar; it's what sugar is. Sugar dissolves in water, and when any substance is dissolved in water, the water has a lower freezing point-- meaning that it's harder to freeze. So, when you put sugar on ice, it's easier to melt.
This doesn't work for just sugar though, it works for anything that will dissolve in water-- like salt, which is why they put salt on icy roads.
Salt
Salt makes ice melt faster than sugar, pepper, or sand. This is because salt lowers the freezing point of water, causing the ice to melt by creating a brine solution that is colder than the surrounding ice. Sugar and pepper will not melt ice as effectively as salt due to their chemical compositions. Sand does not impact the melting rate of ice because it does not lower the freezing point of water.
You need to determine what you think will melt the fastest, and that will be your hypothesis. If you think that pepper will melt it faster, you would say "My hypothesis is that the pepper will melt ice faster than the other variables (sand, salt, and sugar)."
Sugar is not hot, it will freeze, Sugar vs Ice - Ice freezes sugar
One way you can melt sugar ice is put warm water all over it
Table salt makes ice melt faster. Salt lowers the freezing point of water, causing ice to melt by dissolving into the liquid water and disrupting the hydrogen bond between water molecules. Sugar, sand, and pepper do not have the same effect on ice melting as salt.
Salt makes Ice Melt Faster
yes
sugar
It doesn't melt faster but it does melt at a lower temperature. This is because the sugar molecules mix in with the water molecules and prevent them from organizing to form a solid. For more information, look up 'colligative properties,' these are the properties of solutions.

The heat makes it melt.
