In which condition is dissolved oxygen in water more likely to be lower?
Answer and explanation
Correct answer: In warm water
Oxygen is a gas, and gases generally become less soluble in liquids as temperature rises. Therefore, warm water tends to contain less dissolved oxygen than otherwise similar cold water. High pressure generally favours gas dissolution, while fresh, cold, moving spring water is more likely to retain oxygen. The answer describes a tendency, not an absolute rule for every water body.
