The saturation point of a sugar and water solution increases at higher temperatures. This is because...

• Sugar and water molecules move slower and their interactions make the sugar molecules stay together longer

• Sugar molecules move faster

• Water molecules spread out more, making more room for the sugar molecules. Water molecules speed up and collide with sugar molecules more frequently.

• Water molecules actually come apart into separate atoms and react with the sugar
