How might you account for dissolved oxygen concentrations of such a low value at a temperature of 25C?

Other factors must have caused the low dissolved oxygen levels. Bacteria and other organisms can lower the dissolved oxygen of water when they respire aerobically.

Why does metal not rust in boiled water?
Water at high temperature will have less dissolved gases including oxygen.
What is dissoving?
Dissolved Oxygen is the bubbles in water when you splash there's bubbles in the water that is Dissolved Oxygen.
Importance of dissolved oxygen in water?
oxygen is dissolved in water and is also important for the survival of aquactic animals and plants
Can oxygen kill you?
Yes. Long-term exposure to high concentrations of oxygen can be fatal.
As the temperature of an aqueous solution increases what does the concentration of gas dissolved in the solution do?
An aqueous solution has 0.0070 gram of oxygen dissolved in 1000. grams of water. calculate the dissolved oxygen concentration of this solution in parts per million?A. 17ppm B. 27ppm C. 7ppm D. 7ppm
What is the typical limiting factor in streams lake and freshwater environment?
Factors that limit aquatic life are - Temperature - Access to sunlight - Dissolved oxygen concentrations - Availability of nutrients, such as nitrogen and phosphorus
What is the relationship between temperature and dissolved oxygen in an aquatic ecosystem?
The colder the water, the more DO (dissolved oxygen) it can contain.
how does temperature affect the concentration of dissolved oxygen?
Temperature has a direct effect on the concentration of dissolved oxygen in water. As the temperature of the water increases, the solubility of oxygen decreases and the concentration of dissolved oxygen will decrease. Conversely, as the temperature of the water decreases, the solubility of oxygen increases and the concentration of dissolved oxygen will increase. Additionally, warmer water is generally less dense than colder water, resulting in less efficient oxygen transfer.
When water temperature increases what will the dissolved oxygen content do?
The amount of dissolved oxygen decreases when water temperature increases. Warm water is unable to dissolve as much oxygen gas.
Can a wriggler breathe in dissolved oxygen?
Dissolved oxygen (DO) is the amount of oxygen that is present in the water. Worms, fish, crabs and other underwater animals use gills to get oxygen from the water. Scientists generally agree that the underwater creatures need dissolved oxygen concentrations of 5.0 mg/L or more to live and thrive
Which contain the greater amount of dissolved oxygen a lake in the spring or a lake in the summer?
. Temperature directly affects the solubility of oxygen in water. When the temperature of water increases, a portion of oxygen converts from liquid state to a gas. Thus the ability of water to maintain oxygen in dissolved state decreases with increasing temperature. As a result, colder water can potentially contain more dissolved oxygen than warm water. Therefore, a lake in spring contains greater amount of Dissolved Oxygen than the same lake in summer.
Why does dissolved oxygen change when the water temperature goes up?
Because it does.
Normal ranges for dissolved oxygen test?
dissolved oxygen is dissolved oxygen
What is the oxygen dissolved in water is a?
The oxygen dissolved in water is a measure of dissolved oxygen (DO).
Some power plants release hot waste water into nearby rivers or streams fish living in these waters sometimes die from lack of oxygen write a hypothesis to explain what has happened to the oxygen?
Because gases dissolved in water is different then solids dissolved in water, warm water holds less dissolved oxygen than cool or cold water Hot water released in rivers or streams lowers the dissolved oxygen concentrations. Since fish also needs oxygen to live, they can't survive because there is not enough dissolved oxygen in the water for them to live off of.
What can decrease the amount of dissolved oxygen in water?
Sometimes, water can become overheated, like if it is near a factory or power plant. If the water's temperature increases, then the Dissolved Oxygen (DO) level will decrease, which can cause strain or even death for many fish and marine wildlife.
For a fresh water lake to maintain a healthy 0.225 mM or higher concentration of dissolved oxygen required to maintain a healthy aquatic system what is maximum temperature of H20?
For a healthy environment, the temperature of a body of water needs to be inversely proportional to the concentration of dissolved oxygen in it. The higher the oxygen level, the temperature needs to be lower to promote fish growth.
