A student attended an event at a traditional tea room that offered sugar cubes instead of sugar packets. She added two sugar cubes to a cup of hot tea. After she finished drinking the tea, she was surprised to see two small chunks of undissolved sugar at the bottom of her cup. All the sugar dissolves in tea of the same temperature when added from a packet. Which of the following BEST explains why sugar remains undissolved from cubes but not from packets? 1. Adding a cube decreases the likelihood of stirring the tea, whereas adding a packet reminds people to stir. 2. Unlike the packet, the cube is compacted so not all sugar molecule surface areas contact the tea. 3. Unlike a the tea cup with cubes, tea with packets is served in a bigger cup that allows for more tea. 4. The temperature of the tea with cubes was lower than the one with packets.
