Intro

Making Sugar Disappear Faster

You will learn how temperature, surface area, and agitation change how fast a solid solute dissolves in water. A solute is a substance that dissolves, like sugar. Think of sweet tea: sugar stirred into hot tea vanishes quickly, but sugar in cold iced tea sits at the bottom for a while.
