Which statement is the best explanation for the graph?
As temperature rises, gas particles are moving faster and are more likely to enter the solution.
As temperature rises, gas particles are moving faster and are more likely to enter the solution.

As temperature rises, the space between liquid particles increases, allowing more room for gas particles.
As temperature rises, the space between liquid particles increases, allowing more room for gas particles.

As temperature rises, the space between liquid particles decreases, leaving less room for gas particles.

A mother finds her daughter’s mug of hot cocoa on a table an hour after she had been drinking it. As the mother pours out the cocoa, she sees brown solids in the bottom of the mug. How can this be explained?
The cocoa was mixed with hot water, but some cocoa settled as it cooled because the solubility went up.
The cocoa was mixed with hot water, but some cocoa settled as it cooled because the solubility went up.

This would only happen if too much cocoa powder was added in the first place, because the solubility should not change.

The cocoa was mixed with hot water, but some cocoa settled as it cooled because the solubility went down.
The cocoa was mixed with hot water, but some cocoa settled as it cooled because the solubility went down.

All dissolved substances will come out of solution over time. If the mother waits long enough, then all of the powder will appear at the bottom of the mug.
