What effect does stirring have on the dissolution rate of a sugar cube in room temperature water?

• It slows down the dissolution process.

• It has no significant effect on dissolution.

• It speeds up the dissolution process.

• It causes the sugar to crystallize.

How does crushing a sugar cube into a fine powder affect its dissolution in water compared to a whole sugar cube?

• Crushing the sugar cube makes it dissolve slower.

• Crushing the sugar cube makes it dissolve faster.

• Crushing the sugar cube has no effect on dissolution rate.
