Answer :
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.

When you heat a sugar-water mixture, the sugar rapidly dissolves, because the electrons in the heat molecules intensify and work to dissolve the sugar molecules into a solution. The scientific formula the heat molecules break is known as [tex]C_{12} H_{22}O_{11}[/tex], which is also referred to as sugar.
