Question

1. explanation of solubility and temperature which statement best explains why solubility changes with temperature? a. increased temperature raises kinetic energy, allowing more solute particles to dissolve. b. decreased temperature raises kinetic energy, allowing more solute particles to dissolve. c. increased temperature lowers kinetic energy, allowing more solute particles to dissolve. d. decreased temperature raises kinetic energy, allowing fewer solute particles to dissolve.

Explanation:

Increasing temperature raises the kinetic energy of solvent molecules, enabling them to break solute-solute bonds more effectively, thus allowing more solute particles to dissolve, which explains solubility changes with temperature.

Answer:

A. Increased temperature raises kinetic energy, allowing more solute particles to dissolve.
