Sugar is more soluble in hot tea (water) than cold tea (water). So if you put the same amount of sugar into the same amount of water you use less of a percentage of the solubility limit for the hot water and it dissolves faster.

Making solutions can generate or release heat. I've never noticed a change in the solution volume when adding water to sugar, so I will assume the process isn't very endothermic or exothermic.

Good luck!
