A solubility curve of a solid rises upward. What does it mean?
Answer and explanation
Correct answer: Solubility increases with temperature
A solubility curve usually plots the amount of solute that dissolves against temperature. If the curve rises as temperature increases, the numerical solubility is increasing with temperature. Thus more of the solid can dissolve at higher temperatures within the plotted range. A downward curve would indicate decreasing solubility, while the other choices do not describe graph meaning.
