How much time does sugar takes to dissolve in : 1: ice cold water 2: room temperature 3: boiling point

Hey
the higher the temperature, faster will sugar dissolve so sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.
