Question

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

oxygen gas
oxygen gas

sodium chloride crystals
sodium chloride crystals

sugar powder
sugar powder

potassium chloride salt

Answer 1

The solubility of most gases in water tends to increase as the temperature decreases, meaning that **oxygen gas** would be more soluble in cold water than in warm water.

In contrast, the solubility of solids such as sodium chloride, sugar, and potassium chloride typically increases with temperature. Therefore, these substances would generally be more soluble in warm water than in cold water.

Thus, the correct answer is **oxygen gas**.
