How do you describe how sugar dissolves in tea using the big idea of particles?

If you use big pieces of sugar, the particles will dissolve harder ... As the pieces are smaller, as much they dissolve faster.

Sugar is an ionic compound and tea is most likely a polar substance. When the sugar is placed in the tea the molecules of the tea attack the sugar molecules using their negative and positive pulls. The negative sides of the tea molecules pull at the positive parts of the sugar, and vice versa.
