Where Does the Sugar Go in Your Tea?
Drop a spoonful of sugar into a warm cup of tea and stir. In a few moments, the sugar seems to vanish. Where did it go?
The sugar did not disappear. It dissolved. When something dissolves, it breaks into pieces too small to see. These tiny pieces spread out through the liquid and mix evenly with it.
You can prove the sugar is still there with a taste test. The tea now tastes sweet, even though you cannot see a single grain. The sweetness is the sugar, spread through every sip.
Warm water dissolves sugar faster than cold water. The tiny pieces of warm water move around more quickly, and they pull the sugar apart sooner. Stirring helps too, because it keeps bringing fresh water to the sugar.
There is a limit, however. If you keep adding sugar, the liquid cannot hold any more. The extra sugar sinks to the bottom of the cup and stays there as grains.
