No, sugar does not affect the melting point. The melting point of a substance is determined by its chemical composition and structure. However, adding sugar to a solution can affect its boiling point, but that is a different property.
1) Experiment. 2) Ask the question on here. "What is the melting point of sugar?" *)I'll save you the trouble, though. The melting point of Table sugar (sucrose)= around 366.8°F or 186°C
Melting sugar is a physical change because it does not change the chemical composition of sugar. It only transforms sugar from a solid form to a liquid form by increasing its temperature.

Due to their varying melting points (ice 32 and sugar 366°)
Because melting sugar turns color to form caramel. i.e. it has changed and specifically it has undergone a CHEMICAL CHANGE (Or chemical reaction). When melting ice, no chemical reaction occurs, and so it is just a PHYSICAL CHANGE.
Melting is a physical change.

the difference between melting sugar in water or baking cookies with sugar in them is that if you bake cookies with sugar in them you making sugar cookies and melting sugar on water is mixing things together
Melting a sugar cube is a physical change because the substance remains sugar, just in a different form (solid to liquid). The chemical composition of sugar does not change during the melting process.

If sugar is melted, it is still sugar. That makes it a physical change only.

An example of oxidation would be paper burning because it involves a chemical reaction where paper combines with oxygen in the air to produce heat and light. Water evaporating and sugar melting are physical changes, not chemical reactions involving oxidation.
