Question

Which of these substances would be more soluble in cold water than warm water?(1 point) Responses sugar powder sugar powder oxygen gas oxygen gas potassium chloride salt potassium chloride salt sodium chloride crystals

Answer 1

Among the substances listed, **potassium chloride salt** is generally more soluble in cold water than warm water. While many solutes (including common salts like sodium chloride) tend to have increased solubility with rising temperatures, potassium chloride exhibits greater solubility at lower temperatures compared to higher temperatures.

On the other hand, sugars (like sugar powder) and sodium chloride typically dissolve better in warm water than in cold water. Oxygen gas, being a gas, also has decreased solubility in warmer water.

So, the correct response is **potassium chloride salt**.
