Why does H2O + Sugar have a higher boiling point than Water?
I said that H20 + Sugar has a solute of sugar which absorbs some of the heat when boiled.
Is that correct?

No. Remember this.
When a non-volatile solute is dissolve in a volatile solvent, three things happen.
a. the boiling point is raised.
b. the freezing point is lowered.
c. the vapor pressure of the solvent is lowered. (actually, c MAKES a and b true.)
Corollary: The extent to which these three things happen depends solely upon the number of dissolved particles. (that's the i in the delta T = i*k*m formula).

water has no solute to block its rapid movement when heated which causes a lower boiling point.
Would that be somewhat better?
