Which of these substances would be more soluble in cold water than warm water?(1 point)
Responses

sugar powder
sugar powder

sodium chloride crystals
sodium chloride crystals

oxygen gas
oxygen gas

potassium chloride salt

Answer 1

Oxygen gas would generally be more soluble in cold water than in warm water. Gases tend to dissolve better in colder solvents due to decreased kinetic energy, which allows gas molecules to be trapped in the liquid more effectively.

In contrast, solid solutes like sugar, sodium chloride, and potassium chloride typically have increased solubility in warmer water.
