• Q6
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 a 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?
Unlike the packet, the cube is compacted and large in size so not all sugar molecule surface areas contact the tea
Adding a cube decreases the likelihood of stirring the tea, where as adding a packet reminds people to stir
The temperature of the tea with cubes was lower than the one with packets
Unlike the teacup with cubes, tea with packets is served in a bigger cup that allows for more tea

• Q7
While stirring, solid table salt is added to a beaker of water until no more salt will dissolve and salt crystals are visible at the bottom of the beaker. When the beaker is heated, the crystals dissolve. The effect of heat in this situation -
increased the polarity of the salt water
increased the solubility of the salt crystals
reacted with salt so it became water
melted the salt crystals into a liquid
