Question

how does water temperature affect dissolved oxygen levels?
higher temperatures decrease dissolved oxygen.
higher temperatures causes oxygen to solidify.
higher temperature causes oxygen to liquefy.
temperature has no effect on dissolved oxygen.

Explanation:

According to the principle of gas solubility in liquids, as temperature increases, the solubility of gases (like oxygen) in water decreases. This is because higher temperatures provide more kinetic energy to gas molecules, making them escape from the liquid more easily.

Answer:

Higher temperatures decrease dissolved oxygen.
