Assessment
How does temperature generally affect the rate at which a solid dissolves in a solvent?
Higher temperatures increase the dissolving rate.
Higher temperatures decrease the dissolving rate.
Temperature has no effect on the dissolving rate.
Only low temperatures increase the dissolving rate.
What is the primary reason that increasing the temperature increases the solubility of most solids?
Increased kinetic energy allows for more frequent and effective collisions.
Higher temperatures cause solutes to become less dense.
Colder temperatures keep solutes more stable.
Higher temperatures cause the solute particles to expand.
Which of the following statements is true about gas solubility in liquids as temperature increases?
Gas solubility increases with increasing temperature.
Gas solubility decreases with increasing temperature.
Temperature has no impact on gas solubility in liquids.
Gas solubility varies unpredictably with temperature changes.
