Question

question 33 points 2 which of the following holds more dissolved oxygen? water at 100 °c water at 15 °c water at 5 °c water at 25 °c

Explanation:

The solubility of oxygen in water generally increases as temperature decreases. At 100°C, water is boiling (vaporizing), so dissolved oxygen is very low. Among the given options, 5°C is the lowest temperature, so water at 5°C can hold more dissolved oxygen than at 15°C, 25°C, or 100°C.

Answer:

C. Water at 5 °C (assuming the third option is labeled C; if the original labels were different, adjust the identifier but the text remains "Water at 5 °C")
