Solutions Test Scott

Use the graph to answer the following question. Which statement is true?

• Increasing the temperature of water affects the solubility of sugar and salt.

• The saturation of a sugar & water solution is affected by its thermal energy. The saturation of a salt and water solution is less affected.

• Only sugar's solubility is affected by the thermal energy of a solution.

• Sucrose is non-polar.

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

• The volume of the solution would increase

• The density of the solution would increase

• The mass and density of the solution would increase.
