In the students investigation on matter, they add a sugar cube into each of two beakers of water, while stirring the water.

As the sugar crystals disappear, what is happening to the sugar molecules?

• They combine with the water molecules

• They enter the spaces between the water molecules

• They evaporate into the air

• They separate into smaller pieces called atoms

Data was recorded in the previous experiment (dissolving sugar). Shown in the table above. 

The students slowly heat a fourth beaker to 100 degrees Celsius. Using the data they have collected, the students want to predict how long it will take for the sugar to dissolve in this fourth beaker. 

Predict how long it will take the sugar to dissolve (in the 4th beaker), based on the students’ data.
