Question

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

potassium chloride salt
potassium chloride salt

sugar powder
sugar powder

sodium chloride crystals
sodium chloride crystals

oxygen gas

Answer 1

Among the substances listed, **oxygen gas** is more soluble in cold water than in warm water. Generally, gases tend to be more soluble in colder liquids due to decreased kinetic energy, which allows more gas molecules to be trapped in the liquid.

In contrast, ionic compounds like potassium chloride and sodium chloride, as well as sugar, typically exhibit increased solubility in warmer water.
