Most substances dissolve A. at the same rate as all other substances. B. more quickly as heat is removed from them. C. at a constant rate regardless of heat transfer. D. more quickly when heat is added to them.
Question
Most substances dissolve A. at the same rate as all other substances. B. more quickly as heat is removed from them. C. at a constant rate regardless of heat transfer. D. more quickly when heat is added to them.
Solution
The correct answer is D. Most substances dissolve more quickly when heat is added to them. This is because heat increases the kinetic energy of the molecules, causing them to move faster and interact more frequently with the substance being dissolved, which speeds up the dissolving process.
