Question

which of the following occurs as temperature increases?
○ solubility increases.
○ solubility decreases.
○ solubility remains the same.
○ molarity doubles.

Explanation:

For most solid solutes in solvents, increasing temperature provides more kinetic energy to break solute-solute bonds, allowing more solute to dissolve, so solubility increases. Note: This is true for most common solutions; while gas solubility decreases with temperature, the option "Solubility increases" is the standard correct answer for general temperature-solubility relationships taught in basic chemistry.

Answer:

A. Solubility increases.
